Hello Judy,

I don't have a tried/true answer for you, just a couple of things to

#1) If you have access to /var/log/syslog on the mailman machine and if
the mail program logs outgoing messages then there'll be records showing
when the messages went out and whether or not they were accepted.  For
example, a message from bogofilter at bogofilter.org to user at example.com
generated these messages:

Aug 29 23:50:31 nic postfix/smtp[26981]: connect to
mail.example.com[]: Connection timed out (port 25)
Aug 29 23:50:31 nic postfix/smtp[26978]: EE1DA2FF5C:
to=<user+bogofilter at example.com>,..., status=deferred (connect to
mail.example.com[]: Connection timed out)

Both show that the message wasn't delivered because the connection to
mail.example.com failed.

#2) Noticing "comcast.net" in your address, I remember all sorts of
horror stories about how they "filter spam" and don't tell their users.
Apparently they've also introduced a "turn off spam filtering"
capability for an extra $1 per month.  Here in Michigan, comcast has a
bad reputation.  Could comcast be filtering your email for you?
