Hey everyone, I'm not sure I'm on the right list for this one... I have a postfix/dovecot install that was running fine on amazon web services that all of a sudden stopped receiving mail... In my mail log all I get is this: Apr 30 03:16:26 ip-172-31-28-46 dovecot: imap(beth at primelashdiva.info): Connection closed in=595 out=1459 Apr 30 03:16:31 ip-172-31-28-46 dovecot: imap-login:
