Today, Microsoft is ending support for Windows 7. And while MDaemon and Security Gateway continue to support Windows 7, it’s a good idea to consider updating your Windows installation or migrating to an updated system.
Fortunately for MDaemon and Security Gateway users, moving to a new server isn’t a complicated process.
Moving MDaemon to a New Server or OS
Moving MDaemon to a new server using the same directory path involves these tasks:
On the existing server, remove the MDaemon system service.
Deactivate MDaemon & its associated plugins.
Copy the MDaemon directory to the same path on the new server.
Install the same version of MDaemon on the new server.
If you’re moving MDaemon to a different directory path on the new server, you’ll need to update a few configuration files to point to the proper path, but this process isn’t complicated. Simply follow the steps outlined here to migrate to the new server on a new path.
Moving Security Gateway to a New Server or OS
To move Security Gateway, simply make a backup copy of the Security Gateway database, shut down Security Gateway, install Security Gateway on the new server, and then restore the database file.
“Will my software stop working after Microsoft ends support for Windows 7?”
MDaemon and Security Gateway will continue to support Windows 7, but because Microsoft will no longer provide automatic security updates, it’s a good idea to move to a newer operating system to remain secure.
If you’re like me, you want an email client that’s easy to set up, easy to use, and easy on the eyes, and if it works well with MDaemon, then that’s a huge plus!
An email client that fits these criteria quite nicely is eM Client, a full-featured email client that supports email, contacts, calendars and tasks, and works on a variety of platforms and devices. Its touch-friendly design makes eM Client the ideal messaging and collaboration tool for smartphones and tablets.
eM Client is simple, elegant, customizable and easy to set up. Its built-in calendar works seamlessly with MDaemon’s free/busy server to help users avoid scheduling conflicts when planning meetings and events.
Most of our customers are small-to-medium businesses with limited IT budgets across a variety of industries – including healthcare, education, manufacturing, and government. Having a limited IT budget often means having limited staff available for troubleshooting email or tracking down messages, so when considering which email gateway/spam filter you want for your business, one of the main criteria to consider is how easy it is to find messages for your users. Users who are expecting business-critical messages need to know ASAP what happened if that message is not delivered. With Security Gateway, it’s easy to find out if a message was rejected, quarantined or delivered. If it was rejected or quarantined, color-coded transcripts make it easy to determine exactly why the message was not delivered.
At-a-Glance: The Message Log Window
Let’s have a look at the message log and its layout.
Use the buttons across the top to:
Refresh the message list
Search for messages. Advanced search options are provided, allowing you to find messages based on a variety of criteria, such as message contents, delivery date, the result of the message delivery attempt, keywords in a message header, and others.
View message details (providing the same information as double-clicking the message)
Redeliver the message. Note that if the issue that made a message undeliverable still exists then the message will return to the message log with the same status.
Whitelist the sender or sender’s domain
Blacklist the sender or sender’s domain
Press the blue buttons to enable or disable specific columns.
The right-facing blue arrows indicate outbound messages, and the left-facing green arrows indicate inbound messages.
The remaining columns from left-to-right include:
Date (notice the arrow indicating sort order)
The message sender (From)
The message recipient
The message subject
The result of the message delivery attempt (Delivered, Quarantined, Rejected, etc.)
The reason the message was quarantined or rejected (for those that meet these criteria)
The message size
The final message score based on the total score accumulated by all security tests performed
Viewing message transcripts to determine a message’s fate
Now that we’re familiar with the layout of the message listing, let’s review how to troubleshoot email delivery issues.
Key events in a message’s transcript are color-coded for easy identification. In the following example, the message was scanned by SpamAssassin. During this process, it accumulated 1.7 points. It was then scanned by Outbreak Protection, during which it accumulated an additional 5.5 points. Finally, the total message score was tallied with a final score of 12.2 points and was rejected.
We’ve created the following video to help you become more familiar with message tracking in Security Gateway.
Don’t Risk Losing your Life Savings to Scammers. Follow these 10 Tips to Identify a Phishing Email.
Whether you run a Fortune-500 organization or a small boutique, by now you should be aware of the threats posed by cyber criminals to trick you into clicking a link, downloading an attachment, or parting ways with your money.
Modern day email scams are getting more sophisticated, leading to staggering losses for businesses of all sizes. According to the 2018 Verizon Data Breach Investigations Report, phishing was used in 93% of all reported breaches, with email being the main attack vector in 96% of reported cases.
While these figures are staggering, they continue to rise as scammers reap huge payouts from BEC (Business Email Compromise), CEO fraud and other phishing scams.
The real estate industry is a prime target for phishing because large sums of money change hands and there are various weak links in the transaction process. If any step within the transaction process becomes compromised with a successful phishing email, the attacker could gain access to a legitimate email address from which to launch other attacks. The fraudster could then lie in wait, scanning email messages for financial or transaction related details, and then send off fraudulent wire transfer instructions to an unsuspecting buyer, seller, or agent. For example, this happened to a 31 year-old first-time home buyer in San Antonio, Texas. You can read details about this case here, but the short version of the story is that she felt that she was in a time crunch to send in her down payment and finalize other closing tasks, and felt that the title company was dragging its feet. This state of high anxiety made her a prime target for a phishing email she received stating that she had previously been given the wrong wire transfer information, and that she needed to wire her down payment to a new account. With 5 hours left to get everything done, she attempted to contact her title company to confirm the change, but no one responded, so in a panic, she hastily ran to the bank and wire transferred her $52,000 down payment. Unfortunately, she sent her life savings to scammers.
The phishing industry is so lucrative for scammers because the barriers to entry are low relative to potential huge payouts. With botnets-for-hire and Malware as a Service (Maas), spammers have an impressive arsenal of tools at their disposal to propagate their campaigns, so to fight this scourge, an educated user is the best defense against phishing scams. With this in mind, here are my top 10 tips on how to identify and protect yourself from phishing attacks.
Watch out for messages disguised as something expected, like a shipment or payment notification. These often contain links to malware sites. Hover your mouse over any links to make sure they’re safe. Think before you click! Here’s an example using a phishing email I received claiming to come from HSBC.
Watch for messages asking for personal information such as account numbers, Social Security numbers, and other personal information. Legitimate companies will never ask for this over email.
Beware of urgent or threatening messages claiming that your account has been suspended and prompting you to click on a link to unlock your account.
Check for poor grammar or spelling errors. While legitimate companies are very strict about emails they send out, Phishing emails often contain poor spelling or grammar.
Hover before you click! Phishing emails often contain links to malware sites. Don’t trust the URL you see! Always hover your mouse over the link to view its real destination. If the link claims to point to a known, reputable site, it’s always safer to manually type the URL into your browser’s address bar.
Check the Greeting – Is the message addressed to a generic recipient, such as “Valued customer” or “Sir/Madam?” If so, be careful & think twice! Legitimate businesses will often use your real first and last name. In our HSBC example, notice the generic greeting.
Check the Signature – In addition to the greeting, phishing emails often leave out important information in the signature. Legitimate businesses will always have accurate contact details in their signature, so if a message’s signature looks incomplete or inaccurate, chances are it’s spam. In our HSBC example, the sender’s name and contact information are missing from the signature.
Don’t download Attachments – With the proliferation of Ransomware as a Service (Raas), spammers have an easy mechanism for distributing malware-laden spam messages to thousands of users. And because the payout for ransomware can be quite high, even one successful ransomware infection could net the spammer large amounts of money. If there’s ANY doubt about the identity of the message sender or the contents of an attachment, play it safe and don’t download the attachment.
Don’t trust the From address – Many phishing emails will have a forged sender address. The From address is displayed in two places. The Envelope From is used by mail servers to generate NDR messages, while the Header From is used by the email client to display information in the From field. Both of these headers can be spoofed. MDaemon Webmail has built-in security features to help users identify spoofed emails. Many mail clients hide the From address, only showing the From name, which can be easily spoofed. In MDaemon Webmail, the From address is always displayed, giving users a clearer view into the source of the email and helping them identify spoofed senders. Using our HSBC example, I’ve highlighted the actual sender.
MDaemon Webmail will also display information in the Security tag to help users identify messages from verified senders, as shown here.
Don’t Enable Macros – And while we’re on the subject of ransomware, another common vector for ransomware infections is through macros in Microsoft Word documents. These documents often arrive in phishing emails claiming to have important content from HR, Finance, or another important department, and to trick the user, they request the user to enable macros. Never trust an email that asks you to enable macros before downloading a Word document.
While anti-spam and anti-malware tools are quite effective at filtering out the majority of scams, there’s really no substitute for good old-fashioned user education. Know the potential costs to your business and don’t become the next victim!
If you’re the MDaemon or SecurityGateway administrator and need help with your security settings to help block as much phishing as possible before it reaches your users, give us a call or drop us an email support request.
Before the invention of email, mail that arrived in your physical mailbox often contained pamphlets, sales brochures, credit card offers, and product catalogs. Much of this waste was thrown away and ended up in a landfill somewhere. Today, the equivalent and often more annoying nuisance is spam. Spam comes in many forms, and has evolved from dubious product claims, miracle supplements, conspiracy theories, and offers of easy money to more malicious threats such as ransomware attacks and targeted spear-phishing.
While the amount of spam as a percentage of total email traffic has gone down recently, the severity of email-borne threats has increased.
So how can users protect themselves from becoming the next victim to these malicious threats? There are numerous spam fighting tools in MDaemon and other mail servers, but server-side tools are only half of the spam-fighting equation. The other half is user education. With this in mind, here are 10 things users can do to reduce the amount of spam they receive.
Unsubscribe – How often have you been asked by a store clerk for your email address or placed an order online? In either of these situations, chances are you may have ended up on a company’s mailing list. When you receive email from these companies, take the time to open the message and click on the Unsubscribe link. But first, make sure the email is in fact coming from a reputable company (Here’s how). If you’re not completely sure where the email came from, then report the message as spam instead of unsubscribing.
Create a secondary email account – While we’re on the topic of retailers having your email address, you might also consider having a second email address that’s used solely for the purpose of store records or placing orders. This allows you to keep solicitations from these vendors out of your primary inbox.
Keep your email address private – If your email address is visible on social networking sites like Facebook or Twitter, then it’s also visible to spammers. Spammers have tools that can easily detect visible email addresses and add them to their mailing lists. This is why it’s often recommended that, if you MUST use your email address on one of these sites, you mask it by changing its format. For example, type out “at” instead of using the “@” symbol. With the prevalence of Business Email Compromise (BEC) attacks, it’s even more important for executives to be mindful of posting their email address or other personal information, as scammers will use this information to send out well-crafted spear-phishing emails.
Don’t reply to ANY spam or unsolicited marketing messages – Most spam messages use forged sender (return-path) addresses, so replying to a spam message will almost never result in the spammer getting your message. Replying to legitimate marketing messages tells the sender that your email address is valid, and thus, they may continue to send you spam.
Never click on links – Often, when you click on a link in a spam email, it specifically identifies you to the spammer as having received the message. Not only can clicking links in spam messages identify you to the spammer; you can also end up getting infected with malware.
Block Images – Even if you don’t click any links, an image opening in your email can alert spammers to a valid address. Spammers often try to be stealthy by inserting images that are only one pixel wide. If your mail client is configured to automatically open images, spammers can be alerted that your email address is valid. We recommend configuring your email client to automatically block images to reduce spam. You can always choose to view images in specific emails if you are sure the sender and content are legitimate.
Make your email address unique – Spammers often use common names to try to guess email addresses. If your email address is unique, it makes it harder for spammers to guess your email address.
Don’t fall for scams – If you receive an anonymous email from someone who appears to be in dire need, who promises you large sums of money for your small up-front investment, you may be witnessing the familiar Nigerian email scam, or one of many other variants. What are the odds that someone you’ve never met, who’s in a desperate situation, would contact you for help? Don’t fall for this scam.
Never forward email from someone you don’t know – I often see email messages with some type of public service announcement, petition, or other bit of advice, and often, there’s a request to forward the message to your friends. Don’t fall for this, as it’s a prime opportunity for spammers to harvest email addresses.
Blocking junk email is not just the job of the mail server administrator. A well-informed email user can mean the difference between spam that is manageable and spam that is out of control. These ten tips will help you reduce spam, and help prevent you from becoming a victim to phishing or malware.
Nature dictates that we human beings are prone to make mistakes from time to time. For example, if you attached a picture from your toddler’s birthday party in an email to your customer when you meant to attach your customer’s invoice, if you noticed an embarrassing typo after a message was sent, or if you got a little overzealous with your personal information that, after giving it a second thought, might be damaging to your career. Most of us have found ourselves in one or more of these situations at one time or another. That’s why it’s important that your email solution have a Message Recall feature. Message Recall gives you a “second chance” to correct an error or avoid a situation that could be embarrassing or damaging to your career.
MDaemon users have three ways to recall a message.
Using the Recall button in MDaemon Webmail.
Attaching a copy of the sent message to an email addressed to the MDaemon System account with RECALL as the message subject.
Sending a message to the MDaemon System account with RECALL plus the Message-ID as the message subject.
This quick video shows all three methods for recalling an email message in MDaemon Webmail
Let’s face it. We all make mistakes. At one time or another, most of us have gotten a little hasty with the Send button when composing an email, and sent it to the wrong Frank Thomas, accidentally CC’d the customer in an inter-office communication, or realized the email was probably not such a good idea in the first place. These examples can be quite embarrassing, but other mistakes can result in legal trouble for you or your company. For example, healthcare providers can violate HIPAA regulations by sending an email containing protected health information (PHI) to the wrong person. Penalties for these HIPAA violations can be steep, ranging from $50,000 to $1.5 million.
To avoid these situations, your email solution should have a feature that lets you delay delivery of a message. With MDaemon Webmail, message scheduling options are just a mouse click away.
“This is all great, but why would I want to delay delivery of an important email message?”
There are many reasons why one might want to defer delivery of an email message.
Delaying message delivery for an hour or even a few minutes gives you time to take a break from it and review it with a refreshed perspective – providing another opportunity to catch errors you might have missed before.
Some email conversations go back and forth too quickly, so you might respond before you have all the information or ask questions that are already answered in the next message. Deferred delivery allows you to slow the process down so you’re not having to play email tag.
Deferred delivery can help prevent you from sending an angry email response during heated discussions. Allowing yourself a little extra time to re-think your message or to cancel the message altogether can help prevent a great deal of workplace conflict.
For companies that operate globally, deferred delivery allows users to schedule messages for delivery during peak business hours in the recipient’s country, increasing the likelihood that it will be seen.
We demonstrate how to defer delivery of an email message in MDaemon Webmail in this week’s tutorial video.
While it’s true that hard drives are continuing to grow exponentially in storage capacity, many mail server administrators are still finding the need for greater control over disk space usage. An easy way to automate the process of limiting disk space used per-user while still retaining business-related data transmitted via email is to set message and disk space quotas while implement an archiving solution such as MailStore.
By default, MDaemon Remote Administration is accessed via port 1000 at your server’s host name, so if your host name is mail.example.com, then you’d enter http://mail.example.com:1000 to access Remote Administration. You can also use a secure URL – for example: https://mail.example.com. The URL you would use depends on the settings you have configured in MDaemon under Setup | Web & IM Services | Remote Administration | Web Server (and SSL & HTTPS).

If you work in IT or manage a mail server, then you probably know that the vast majority of global email traffic consists of spam. However, if you’re an end user working for a small business in healthcare, manufacturing or education, the following statistic might surprise you:
In June 2018, spam made up a staggering 85.32% of all global email traffic.
A good spam filter & email gateway will filter out most of these malicious email messages circling the globe so that users and administrators can spend more time focusing on their business.
SecurityGateway for Email Servers was designed to make it easy for small-to-medium businesses to manage their inbound and outbound email security needs without taking up too much time that could be spent on more business-related tasks. It reduces the workload on administrators by providing automated user & domain creation and periodic quarantine report emails for end users. The focus on today’s “30-Second Email Tips” video is to demonstrate the quarantine report emails which allow users to manage their own quarantines so you can spend more time focusing on your business.
Many of SecurityGateway’s security settings (including heuristic and Bayesian analysis by the spam filter, DNS blacklists, SPF verification, DKIM verification, DMARC, and others) can be configured to perform one of three options for messages that fail a given security check:
Accept the message (and optionally place a tag in the message subject and add points to the message’s spam score)
Refuse the message
Quarantine the message
For messages that are placed in the quarantine, reports can be sent out to users so that they can decide what to do with these messages. Options provided are:
Release the message from quarantine
Always allow (whitelist) messages from the sender
Blacklist messages from the sender
We’ve created the following video to demonstrate these features.
SecurityGateway helps meet the needs of businesses that want an additional layer of security for their existing email server and businesses running Microsoft Exchange or another mail server that has cumbersome controls or a confusing interface – helping simplify the process of scanning inbound and outbound email for malicious content.

I’ve heard various opinions on what to do with an MDaemon account belonging to someone who has left a company. In a recent post on our community forums, an MDaemon administrator had set a former employee’s account to Frozen, and then configured an auto-responder for the account. Frozen accounts cannot send outbound email, and the user of a frozen account cannot check for new email.
Account is FROZEN (can receive but cannot send or check email)
Select this option if you wish to allow the account to receive incoming messages but prevent it from being able to check or send messages. This is useful when, for example, you suspect the account has been hijacked. Freezing the account would prevent the malicious user from accessing its messages or using the account to send messages, but it would still be able to receive its incoming email.
Let’s say an employee has left the company. As the MDaemon administrator, I don’t want that employee’s account to be used, so I place it in Frozen status via the main Account Details screen of the account editor, as shown here.
Now let’s say I’ve enabled an auto-responder for the account, as shown here.
In the following example, I’ve created the account email@example.com, and have configured the auto-responder.
When I send a test to firstname.lastname@example.org from email@example.com, the MDaemon server hosting the @brad.ssllock.com domain places the message in the frozen account’s mailbox, but the user is unable to log into webmail or access the inbox via another email client. When MDaemon then tries to send the auto-responder that we enabled for the frozen account, the message is moved to the Holding queue and the following is written to the MDaemon logs:
Mon 2018-06-18 11:18:33.406: Session 042192; child 0001
Mon 2018-06-18 11:18:33.406: Parsing message <c:\mdaemon\queues\remote\pd50000000056.msg>
Mon 2018-06-18 11:18:33.406: * From: firstname.lastname@example.org
Mon 2018-06-18 11:18:33.406: * To: Training@mdaemon.com
Mon 2018-06-18 11:18:33.406: * Subject: RE: Test to Frozen Account with Auto-Responder
Mon 2018-06-18 11:18:33.406: * Size (bytes): 3822
Mon 2018-06-18 11:18:33.406: * Message-ID: MDAEMON0005201806181118.AA1812640@mail.brad.ssllock.com Mon 2018-06-18 11:18:33.421: Message moved to holding queue because sending account is disabled Mon 2018-06-18 11:18:33.421: SMTP session terminated (Bytes in/out: 0/0) Mon 2018-06-18 11:18:33.421: ———-
The result is that the auto-response never gets sent because the account is frozen.
Rather than freezing the account, you could simply change the account’s password so that it can still accept mail and send auto-response messages. This can be done via the main Account Details screen, as shown here.
If you prefer to freeze the account instead of changing its password, another option would be to create a content filter rule that would send your desired response to the original message sender instead of using the auto-responder. That content filter rule would look something like this:
In this example, I created a rule that sends a reply to the sender of messages addressed to email@example.com using the “Send a NOTE 1” action. I then entered the $SENDER$ macro and the desired response. This message will be sent back to the message sender in response to a message originally sent to the frozen account.
You can get pretty creative with MDaemon’s content filter to perform a variety of tasks, so hopefully you found this helpful!
