I just installed zimbra and after some tests I checked that my outgoing emails are reaching the destination, but the incoming emails are not reaching the mail accounts, but in the Mail Queues I can see the Sender Domain, Sender and receiver address and the messages, But at the error panel it says:
connect to "server.domain[x.x.x.x]":7025:connection timed out XX messages
Can anyone explain me what I did wrong, what is missing?
My server is behind a PfSense firewall, but I donīt think that this is the problem, there is an Nat rule allowing connections, iptables has some rules , but there is an rule accepting tcp:7025.
Additional to the message above, there also apears:
delivery temporarily suspended: connect to "server.domain[x.x.x.x]":7025:connection timed out XX messages
