Are you saying this was a notice that his subscription was disabled due
to bounces. Check Mailman's bounce log for information (grep the bounce
logs for the users address).

If it is a warning because his subscription was disabled by bounce,
check your MTA logs for possible bounce reasons.

Also, it is good to turn on the bounce processing notices, particularly
bounce_notify_owner_on_disable, so that thi lis owner gets a copy of the
bounce DSN that caused the disable.

It is possible. I have set up opendkim to sign list mail on at least
three servers. Get opendkim from <http://www.opendkim.org/> or your
package manager. The README in the distribution has a section on
configuring for mailing lists.
