Why is your MTA returning 4xx status to Mailman as a bounce? Your MTA
should be retrying these and eventually delivering them.
If you're getting "bounces" like "message undeliverable after 4 hours;
will keep trying until message is 5 days old" Mailman should be
ignoring those. If it isn't, send me a complete, raw copy of the DSN,
and I'll fix it and tell you how to fix yours.
