Mailman itself has no such option.  See other replies for possible
ways to craft your mail to get this effect, although reliability is
not 100%.

No cumulative statistics are kept, but bounces are logged to
mailman/logs/bounce (relative to the Mailman installation prefix,
typically /var/lib/).

You can get the list of members disabled due to bounce with
"mailman/bin/list_members --nomail=bybounce".

Internally Mailman keeps statistics about bounces since last
successful delivery for each subscriber.  These statistics can be
accessed using mailman/bin/withlist and writing some code.  (Mark may
have a script that has not byet been included in the distribution.)
I doubt this is very useful, though, since it is likely to reset
