I've been running Postfix / Dovecot for about 9 months on a CentOS system I maintain and use for shared hosting, and have been happy with it. However, there are two "features" that I'd really like to provide to my clients: 1) The ability to change their password, and/or add additional email addresses from inside a web interface 2) A better webmail interface (of course, most of my clients us Outlook and other desktop programs, but I need to offer them something useful online too).

Users can currently use Horde, but very few of my clients like the look & feel of it, and of course, there's no way to change one's password.

Yesterday, I launched a 2nd server to use for Nameserver redundancy purposes, as well as to migrate the mailserver over. I was looking at - and leaning towards - installing Zimbra, as I've actually used it before.

However, I didn't realized until now how much resource requirement it has. 1GB of RAM for a dedicated (VPS) mail server for only about 15-20 email accounts seems a bit much.

Are there any other good alternatives you guys would suggest, and/or modifications I could make to my current Postfix / Dovecot / Horde configuration on which to improve upon?

You might take a look at SME server. It includes a pretty light base platform built with CentOS, qmail and Horde, but you can also add other webmail/groupware options on top of it - like Roundcube, GroupOffice, etc.

Self-password management is already in SME itself and I think depending on the webmail/groupware add-on, they may also be options for self-account creation as well.

If you're referring to, then I don't think this is a very good solution, as I would only need about 1/4th of its functionality, and I'm not trying to build a network behind it. Thanks for the suggestion, though. – David W Jul 4 '11 at 15:58
Oh well. You don't need to run every feature that it is bundled with and you can just as easily remove functionality as well based upon your specific needs/comfort level. – user48838 Jul 4 '11 at 18:16
