Version 3.1.13 is old you should upgrade to dbmail 3.1.17 or dbmail 3.2.3.

I have built a 3.1.17 package on friday, but I did not dare to install it
before the weekend.
3.1.17 is up and running now.

There were 16 crashes with dbmail-3.1.17 within the last 50 hours, always
the same error (see attached file dbmail.3-1-17.crash.txt)
This is above the average of 5..6 crashes per day we had with
dbmail-3.1.13.

A few minutes ago I switched to dbmail-3.2.3.
I'll report if that made any difference.

Do you use SSL with dbmail?

If so, please deactivate it and use a ssl proxy, I use nginx für imap und
pop3.
