Who uses Zimbra as a mail server?

I'm looking for a mail server with awesome web interface. I like Zimbra's web interface the most.

From your experience, is it really that resource intensive as it described? Which minimal hardware will you take for it?

    Zimbra is the best!! I've not found any other linux alternatives which are better than it.

    Best to run it on a dedicated machine with 3 to 4GB of RAM. It won't work on OpenVZ based servers due to Java memory issues or something, not tried it on any other virtualization platform.

    The lowest RAM I was able to run it on without issues for less than 5 users was 2GB (on a Xen HVM server) although you can disable a lot of features and get it down to 1-1.5GB but then you'd be better off running Horde or Roundcube instead.

  • It basically looks like a bloated Horde.

    Catalyst Host - Pie Approved!

    +1 for Horde, or Roundcube (just for mail). Zimbra eats RAM imho... Have you looked at Zarafa?

  • may be you can try iRedMail :D

    Do you know Lake Toba?

  • I actually gave Citadel a go, but its IMAP implementation does not work in most email clients (it does not follow the standard).

    So it was a no-no.

    The open source features suck, you have to pay to get almost basic functionality!

    You could probably get away with Axigen's free mail server I've managed to run it on a 512MB OpenVZ without any issues, with roughly 5000 emails coming in daily to be piped through a catch-all email address.

    It wasn't the most elegant setup by any means, but it worked!
