It is unlikely that it's related to mailman. For what it's worth,
even Eric Allman says you shouldn't edit your .cf files directly:
Always build your .cf from a .mc, and treat the .cf like a binary
file. The FAQs at sendmail.org are pretty good. This page:
has excellent information on locking sendmail down against spam and
other fun stuff. It looks BSD specific, but it isn't really.
That said, if you can switch to a modern MTA (Postfix, etc..), do so now.
