Hi, we are testing ZCS, it works quite well using just one server, but when we tried the distributed approach using one LDAP Server, one MTA server and one Mailbox Store server, the messages do not travel anywhere.....
I sent from an outside email, no bounce errors but no message appears in my zimbra mailboxes, I sent from Zimbra and nothing arrives to an external account.

Any ideas ? or where can I find any documentation about how to configure the distributed servers approach other than the nice diagram ? (a step by step guideline would be nice)

Thanks and congratulations for a great email product.
