  • Lacks an LDAP server

  • Additionally, content filters can remove certain messages globally, per domain, or per user.
  • ISMail includes an interface to external virus scanners.

Guide Review - ISMail 1.4.3 - Mail Server

Mail servers have an image of not being the easiest software to use. That's not true for ISMail, however. Administration of the SMTP, POP and IMAP servers happens in a single and simple dialog.

Of course, this simplicity stems in part from the absence of more advanced features. But all the essential functionality is there, and important anti-spam measures, too.

It's great that access can be controlled by IP address, but this feature would be even more useful if it could be set individually for the protocols. A plug-in enables Web-based account access, and the option to include external virus filters completes the ISMail package.

Unfortunately, ISMail does not support secure TLS/SSL connections.
