	We have some more information at 
The comment in question is:

     # Note: We need to be sure two messages aren't ever sent to the same list
     # in the same process, since message ids need to be unique.  Further, if
     # messages are crossposted to two Usenet-gated mailing lists, they each
     # need to have unique message ids or the nntpd will only accept one of
     # them.  The solution here is to substitute any existing message-id that
     # isn't ours with one of ours, so we need to parse it to be sure we're not
     # looping.
     # Our Message-ID format is <mailman.secs.pid.listname at hostname>
