Code:
tail -f mail.err
Dec 6 06:25:02 ns3002344 exim4: ALERT: exim paniclog /var/log/exim4/paniclog has non-zero size, mail system possibly broken
Nothing more after sending e-mail. I checked /var/log/exim4/paniclog a lot of times, nothing new there but to be sure, here's the content:
Code:
cat /var/log/exim4/paniclog

I trimmed the log as it is too long for the post. As the problem is recent (about two months or so), I suppose this has nothing to do with it.
Code:
tail -f mail.log
