Hello,

I've just setup Ubuntu 12.04 following this guide and I've tried sending an e-mail to myself, but I don't receive the e-mails. I just cleared my mail log and attempted to e-mail myself again to generate the following log. I'll appreciate any help.

This has now been resolved. My problem was related to this line:

Jun 17 17:30:35 n3rve postfix/trivial-rewrite[3983]: warning: do not list domain n3rve.com in BOTH mydestination and virtual_mailbox_domains

To fix, I had to remove my FQDN (also my hostname) from main.cf.

mydestination = localhost, localhost.localdomain

After making that change I restarted and reloaded postfix, and mails worked as expected.
