[Mailman-Users] Using VERP to avoid sobig bounces?

[Joe Orton]

If we turn on VERP, how is mail to the unqualified -bounces@
address processed? Is it ignored?

At the moment we are frequently getting subscriptions disabled
on the webdav.org lists (which don't use VERP) by stray SoBig
bounces using a real subscriber as the return address and
-bounces@ as the recipient.

Will turning on VERP avoid this headache?

Also, following the URL in the automatic "your subscription
has been disabled please go to this URL to confirm" always
results in an "Invalid confirmation string" message, any
ideas how to fix that?

Regards,
