If you’re considering setting up an email server for your business, you’ll need to consider the following factors:
- Domain registration
- How to tell other mail servers where to send email addressed to your domain (DNS)
- Encryption requirements (SSL)
- How to protect your domain from abuse by creating PTR, SPF, DKIM and DMARC records
- How email addressed to your domain will be received by the mail server (via direct delivery, or by downloading mail from an ISP or other host via DomainPOP, MultiPOP, ETRN or ATRN)
- Outbound mail delivery considerations, such as whether to send outbound messages directly to the receiving mail server, or through a smart host or ISP
- ISP restrictions (some ISPs block port 25)
- Hardware considerations
- Internet connection
- Protection from spam & viruses
Settings may vary depending on your specific needs and business environment. Our new How-to/Best Practices guide: Deploying a Mail System, will help you get started with your new mail server. You can find this and other how-to guides on our Literature page.
