Since 
"Alan Silcott, Network Admin" <1234 at hotmail.com>
Is a valid email address per RFC (when the obscured address is fixed up),
the fact that the "," inside the quoted information causes problems is a
mailman error.

Your MTA should give up and bounce the message after the length of time in
its configuration.  Or, if you have access and knowledge, you can delete the
message from the MTA's queue...how varies a lot by MTA.

One might wonder why North Kitsap's server fails a non-existent user using a
temporary failure code (450 rather than 550).  That causes servers around
the world to retry for several days before giving up.
