I need to setup a mail server, and it will be my first one. We have a few users, and several domains. Usually, the other domains are simple redirects.
If I have to leave for some reason, I need to know that the next administrator will have some hope of resuming where I left off, without having to redo everything.
How does QMail compare to Postfix and Sendmail in the areas of:
- Ease of Setup (Do I have to write lots of code to just make it work?)
- Ease of Maintenance (Adding users, moving users, adding aliases, adding domains...)
- Security (Does it have lots and lots of vulnerabilities, does it interface nicely with SpamAssassin?)
- Neat Features (Web management interface, user features)
