Dear all,

Having done some more research I've cleared those two messages (yes,
there were only two) from out of the bounce spool, and the bounced.pl
error messages have gone away.

But sympa itself is still not working properly, and taking up vast
amounts of system resources:

top - 12:26:12 up 2:21, 1 user, load average: 2.80, 2.60, 2.20

0.2% si

Mail is passing through the qmail service on the server without
problems, but mail to sympa and its aliases is not. Lists are not being
served and there are now several hundred messages, going back over two
days, in /home/sympa/spool/msg - how can I get them moving again? There
also seem to be tasks backing up in /home/sympa/spool/task

Any ideas?

Thanks,

Nick
