Recently the moderator of a mailing list I host got a Mailman error.  And this 
is what was in Mailman's error log:

This is on a CentOS 5.11 system (64bit), with Mailman 2.1.16 that I built as
an RPM from the sources.

Is this something I need to worry about?  Or is it likely to have been caused 
by an illformed spam message?
