Is the stuck message very big? Large messages can sometimes take a long
time to process, especially if you are using SpamAssassin. Some things
that might help:
- Check the message size in your filter and simplify the processing if it's
big. For example, spam messages are seldom over 20-30kB; don't run
SpamAssassin on very large messages.
- Increase the timeouts both for the multiplexor (the -b flag) and the
correspoding time in the Sendmail configuration file.
- Try to capture a problematic message and run your filter on it by hand.
Make sure there's not an error in the filter which causes an endless loop.
- Enable logging (the -l flag to the multiplexor) to see if it sheds any light.
Regards,
David.
