[Mailman-Developers] Important Mailman 2.1.9 to 2.1.10 upgrade note.

Hash: SHA1

Actually, this note really applies to just restarting mailman a Mailman
2.1.9 installation, with or without upgrading to Mailman 2.1.10. But in
installations that just 'run' without intervention, this restart may not
occur until an upgrade.

There is an error in Mailman 2.1.9. In the introduction of the backup
and recovery of queue entries, we neglected to remove the backup queue
entry for an unparseable message. Thus, if you sometimes receive
unparseable messages which are ignored, you may have an accumulation of
.bak files in qfiles/in from these messages. When you restart Mailman,
these will all be reprocessed, resulting in a flood of error log entries.

There is no real harm done, but it would be a good idea when upgrading
to stop Mailman and remove any qfiles/in/*.bak files.
