[Mailman-Users] Excessive cpu usage

[Arnar Birgisson]

Hi there..

I verified this.. the MTA seems to be configured correctly. Since
switching to Exim recently, mailman lists have worked as they should.

As I mentioned earlier, some files are constantly being created in the
out queue directory. I wasn't right when I said earlier that there was
no traffic, apparently there is one message in the out queue, according
to the contents of those files.

What makes me unable to diagnose the problem however is that nothing
shows up in neither the mailman log files nor exim's log files.

The FAQ that is included in the Mailman download indicates that it
could also be a problem with your MTA.  Make certain that your MTA
isn't set up to do DNS lookups on each address.
