After installing Zimbra on Debian 4 I log on to the admin console and creating a couple of accounts. Checking that all services are running (monitoring -> serverstatus). Only thing installer complained about was the fact that none of the MX records pointed to the servers IP (due to the fact that I havent changed the DNS yet..). Now, since all services are running and I can successfully log on to webmail I now change the dns settings for my domain so that mail.mydomain.com points to my IP.. I can see via Tools -> mail queue that mails are ticking in, but ending up in the "deferred" tab and none of em ends up in my mailbox. Any pointers to what I can have done wrong?
