What Mailman version is this? Current Mailman (2.1.6) is pretty good
about weeding out addresses with non-printable ascii characters. In
particular, it won't accept whatever characters were displaying as a

Mass subscribe allows subscribing with or without notifications
regardless of list settings.

The notifications are created and placed in Mailman's virgin queue
(qfiles/virgin/) and then processed by VirginRunner and placed in the
out queue (qfiles/out). They are then picked up by OutgoingRunner and
delivered to the outgoing MTA.

You can stop Mailman (bin/mailmanctl stop) and then simply delete files
from the queues. You can use bin/show_qfiles to examine qfiles if you
are in doubt about what to delete.

Of course, none of this deals with messages that have already been
delivered to the MTA and are queued there.
