Hello,

I'm running dovecot with getmail for several months already, but today it's always crashing: "getmailrc: operation error (child pid 2995 killed by signal 6)".

The deliver process aborts due to an unknown reason.

How can I find out which message is causing the crash?

It would be very helpful, if the message's subject and receipt time could be logged in case of an abort or anything else that could help identify the corrupt message. This would also enable me to send You the message for further investigation (if appropriate).

Kind regards Peter
