Is Zimbra For Me !?

Hi,

I'm thinking of upgrading a current mail server to use Zimbra and have a couple of questions I hope you don't mind answering !?

I own the following domains ...

http://ubumail.com
http://ubumail.co.uk
http://ubumail.org
http://ubumail.net
http://ubumail.eu

As long as all these domains point to my server and I have DNS setup properly using BIND9, can Zimbra handle all the incoming mail or is it restricted to a single domain !?

If it can, can it handle mail for the same user at different domains !? ie
mic@ubumail.com would be a different person than mic@ubumail.co.uk and therefore would require seperate inbox's ... is this possible !?

Finally, from what I've seen, it is possible to connect to Zimbra from any IMAP client. Am I correct in thinking this !? The reason I ask is we currently use squirrelmail on the existing mail server, and I would prefer to stick to that for the time being until all the behind the scenes work is complete so the users have as little disruption as possible, introducing the Zimbra webmail client at a later stage !?

Also, what's the largest number of users the suite can handle !?

Hope you don't mind me asking so many question :)

Thanks

Yes, Zimbra can handle multiple domains (it does routing via postfix, so if postfix can do it, Zimbra can do it)
Yes, Zimbra can communicate with any IMAP client
Zimbra's user count varies by machine

Search the forums, there are a few threads describing user load on a particular machine.

I have two servers as well, and the second one was not running the MTA, but I enabled it in the web interface. Now when I start the second one, I get this:

After the zmcontrol start finishes, I am able to telnet to the mta, so it's obviously running anyway, but I get this error.

oops wrong window? ;)

so ldap is running on server1? run this on the second machine (subbing the hostname) to see if the auth host is set properly:

zmprov gs SERVER2 | grep -i mtaauth

Yeah, looks like I did reply to the wrong thread.....

LDAP is running on server1, but not server2.

np. try this (obviously, replacing the server names):

zmprov ms SERVER2 zimbraMtaAuthHost SERVER1

That fixed my problem. Thanks!
Also, If I set up my MX records so that either box can receive mail, will they each route mail to the correct mailbox server correctly? And along those lines, can the users of one server relay through either server?

Yes each MTA can do LDAP lookups to find the right mailbox to deliver mail locally.
