Topic: Unable to receive external mail. No record in logs.
==== Required information ====
- iRedMail version: 0.8.4
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): MySQL
- Linux/BSD distribution name and version: Ubuntu 12.04
- Related log if you're reporting an issue: ?
I am able to send/receive from internal accounts, send to external accounts, but not receive from external accounts (gmail, etc). I cannot find any log messages related to incoming mail. I have a feeling this may be DNS related, as I've tried numerous troubleshooting methods on this board, and DNS is the area I'm least confident with.
What steps should I take on Ubuntu 12.04 to verify that my DNS records are properly configured for iRedMail?
