This sounds like your MTA has at some point advertised the alias
of your -outgoing address. You can block this using sendmail's
virtusertable feature, and this line in /etc/mail/virtusertable;
my_list-outgoing@my_domain.com error:nouser User unknown
Rebuilding this map file does not require restarting sendmail.
Another work around, make sure majordomo is a "trusted" user of
your MTA, so sendmail does not complain in the headers of the
distributed mail. Change the resend target to my_list-today,
and rename the my_list-outgoing alias to my_list-today.
Rebuilding the aliases file does not require restarting sendmail.

Or to disable anybody else sending messages to the list using the my-list-outgoing@my_domain.com address (which I didn't create)? I really don't know how the subscribers got those unwanted messages if the list is set as "moderate = yes"...
