A Fresh New Look & New Features for SecurityGateway 4.0!

SecurityGateway_logo_transparentA company’s greatest asset is its customers, and here at Alt-N, we strive to listen to our customers’ needs. A direct result of that effort was the creation of the Alt-N Idea Engine, which allows customers to submit feature requests and other ideas to improve our products. Many of these ideas have made their way into our products, and many more are being considered for future versions.

Recently, we introduced some exciting new features to MDaemon, including a flexible Remote Administration interface and enhanced security via DMARC (Domain-Based Message Authentication, Reporting, and Conformance). I’m pleased to announce that these and other great new features have now been added to SecurityGateway!

A brief overview of key new features is outlined below. For a complete overview of all new features and enhancements, click here to view the SecurityGateway Release Notes.

Flexible, Mobile-Optimized Web Interface

With the proliferation of handheld devices and an increasingly mobile workforce, users will benefit from an updated, responsive web interface that is optimized for mobile devices. The format of the information displayed is dependent on the size of the browser window, so whether you’re on a desktop PC, a tablet, or a mobile phone, the interface adjusts for a more user-friendly experience regardless of what type of device is used.

Enhanced Anti-Spoofing Support with DMARC

DMARC (Domain-Based Message Authentication, Reporting and Conformance), enables domain owners to direct the actions to take when handling messages purporting to be from their domain(s) but were not actually sent by them.

Bind Domain to Its Own IP address

For servers that have multiple IP addresses and multiple domains, each domain in SecurityGateway can now be bound to its own IP address. This allows messages from a specific domain to be sent only from its assigned IP address.

Blocking Incoming Email by Country

Are you receiving a lot of inbound email to MDaemon or SecurityGateway from a particular country?

Does your company do business with this country?

Do your email users only need to send and receive email within your own country?

If you run a small business and all of your clients and suppliers are local, then chances are you’re not going to be sending email to certain countries across the globe. Depending on the type of business, companies may want to block all incoming connections from these countries. This is especially useful because a lot of international email traffic contains spam, malware, phishing attempts, and viruses. Taking the time to deal with these types of messages can lead to lost productivity.

There’s an easy way to block these connections. In this video, I show you how to block mail by originating country using the DNS-BL features in MDaemon and SecurityGateway.

If you’d like more information on MDaemon’s security features, then visit the Email Security link under our MDaemon product page.

Blocking Messages based on Keywords in SecurityGateway

If you work in real estate, you are not likely to receive email with pharmaceutical-related content, and if you work in the medical field, you’re not likely to receive email about stock tips or account-related notifications from PayPal. With SecurityGateway, you can create content filter rules to filter out messages that contain words that are not relevant to your business. You can filter based on the sender, recipient, IP address, message subject, message body, or any header found within the message. I’ll show you how in the following brief tutorial video.

SecurityGateway is a software-based email gateway/firewall that can be installed in front of any Exchange or other SMTP mail server, allowing you to block malicious content, such as spam, viruses, malware, and phishing attempts, before it reaches your mail server. You can learn more about SecurityGateway here.

Rebuilding the Bayesian Learning Process in SecurityGateway

SecurityGateway and MDaemon both feature Bayesian learning, which allows administrators (or users, when authorized) to feed samples of spam and non-spam email messages to designated public folders. By default, when 200 samples of spam and 200 samples of non-spam have been placed in these folders, the Bayesian learning process will process these folders and feed their contents to a database of what are known as tokens – snippets of spam-like and ham-like (non-spam) content, basically. We all know that we humans are not infallible – people make mistakes, so it’s possible for messages to be fed to the wrong folders. When this happens, users may begin to receive more false-negatives (spam that was not caught by the spam filter) or you may accumulate a number of false positives (legitimate email messages that were flagged as spam by the spam filter). When this happens, it may be necessary to rebuild the Bayesian database. You may recall that I posted  a blog entry awhile back on how to rebuild the Bayesian database for MDaemon. You can read that post here. For SecurityGateway, the concepts are the same, but the navigation and file locations are different. The following tutorial video explains how to rebuild the Bayesian database in SecurityGateway.
