I am planning to setup a large-scale zimbra platform using Zimbra OSE.
I have a multi-server setup involving:
* 1 Zimbra LDAP (master)
* 2 Zimbra Mailboxd
* 1 Zimbra MTA.
My question is quite simple, but I'm not sure I really understand how it is working.
In a single-node setup, zimbra-mta spam-trainning is looking to 2 mailboxes where users can drop spam. But how does it work when we have separates MTA and Mailbox server ?
As an example, when users on the first mailbox server drop mail in the spam training account, the MTA server (which is not on the same server) _must_ connect to this account to learn spam as SpamAssassin/ClamAV is not running on mailbox server. But I'm not sure it does...
Can you help me to understand how it work.. or not
Thanks a lot.
