I remember it took some effort to get it set up initially but it's been pretty hassle free since. I don't mess with it much at all. We haven't upgraded to the most recent major revision because they quit supporting RHEL 5 (we're using CentOS) and only support 6, and the upgrade path is not trivial. I believe you have to install your current version on 6, do a restore, then do the upgrade. Not huge, but more than I've had time for so far. Something else always seems to take precedence. Still, we've been pretty happy with Zimbra. The Web UI is pretty nice and the IMAP support is also very good. It bundles Clam and Spam Assassin so you don't have to configure them manually. From the command line, I was able to add anti-spam DNS block lists. It seems to work pretty well, but some spam does get through. <div><br></div><div>You do need to dedicate a box or VM to it though.

<font size="-1">I'm in the need to figure out a new method of email,
that does no include Exchange.<br>
<br>
Currently I use CentOS to fetch all our our mail from our provider
and store locally. Users then use IMAPS and SMTP to receive and
send.<br>
<br>
We get hammered with Spam that has nasty attachments. One user
asked me what we could do about this. My thought is that I'm
going to have to install a real commercial SPAM firewall. I also
looked at Google business email. My options currently are to look
at purchasing a Baracuda appliance to cut down on the crap or use
Google email services. <br>
<br>
With the Baracuda I'll stop fetching mail from the provider and
smiply chane our DNS MX records to send mail directly. I'm not
sure how it will feed email to my mail system or if it is the
IMAP/SMTP server. Anyone use one of these devices?<br>
