This is what I wrote is a reject message for a post to

Your members are apparently being unsubscribed by automated bounce
processing. You can adjust the settings or turn off bounce processing
all together from the list admin web interface, but the real solution
is to discover why apparently valid addresses are bouncing. You might
be able to determine this from Mailman's logs and/or the MTA logs, but
if this is a hosted Mailman, you will need to contact the host for

To follow up or if you have other questions, please join the
mailman-users at python.org list at
and post your request there.  Note that this is a publicly
archived list.  Do not post personal information that you
don't want to expose to the world.

However, if yours is not the same list, there is probably some
server-wide mail delivery issue that is causing excessive bouncing.
