Whilst the world seems to be moving email to “The Cloud”, rightly or wrongly I remain reluctant to give up the control of our own mailserver. For over ten years now we have been using a combination of the following open source applications:
- Postfix MTA with Amavis + Spamassassin
- Dovecot IMAP server
Whilst these are super-stable and bulletproof solutions, the main issue with such a solution is the administration – setting up users, changing passwords, vacation notifications, sieve etc. It is also a lonely business administering a custom mailserver, where set-up is never going to be completely standard.
