Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I'm looking for a good open source Linux mailserver for a small (internet) company. Which is still updated frequently. I'm developing the website with PHP and MySQL if that's important. Anybody any idea(s)?

Thanks

can't go wrong with postfix. –  imm Mar 4 '12 at 21:11

postfix is RHEL6 default now so it isn't going anywhere. That also means a lot of enterprise support. –  Belmin Fernandez Mar 4 '12 at 21:27

Postfix. It's very reliable, still developed and used by many mail servers. Most Linux platforms support it. Works fine with php and mysql. If not postfix, then check qmail: same same but different.

For god's sake, don't use qmail unless you have a very good reason: shearer.org/MTA_Comparison#qmail and that's from 5 years ago. qmail is even more out of date now. –  cjc Mar 4 '12 at 21:33

-1 QMail hasn't been updated in about 13 years. It's pretty much irresponsible to recommend it at this point. –  Chris S Mar 4 '12 at 22:10
    
Oops. I didn't know qmail was outdated. So then I only recommend postfix. –  öde Mar 5 '12 at 17:09

Postfix and Exim are the two most common mail servers for Linux. I use Exim without any problem ever, but I thing people using Postfix don't have problem either.
Other choices include qmail. Very famous too because of its origin. A little less common.

QMail hasn't been updated in something like 13 years. I don't know why people even mention it let alone recommend it. –  Chris S Mar 4 '12 at 22:09
    
@ChrisS ...let alone roll it into default CentOS 6 VPS images like what I just got. :'( –  Wesley Mar 5 '12 at 0:19

you could use Dovecot IMAP Server.

If you need to integrate it with your website / intranet based on PHP/MySQL, you can use the class http://www.phpclasses.org/package/2351-PHP-Access-IMAP-mailboxes-without-PHP-IMAP-extension.html

Works with Postfix and EXIM, too.

hope this helps!
