Hello, I experienced issue with my ispconfig3 installation, recently I noticed that my phpmailer doesn't deliver emails, so I logged to squirelmail and sent some test mail to my main mailbox, but it was not delivered, after sending from my main mailbox, nothing happened, i didn't even received error message from google. Then I decided to reboot VPS, and suddently few mails were delivered to both mailboxes, how to find out what was wrong? How to prevent such fails in future?
92.222.161.66/test.txt There is var/log/mail.log, it looks like I have no other mail related logfile.
