[Mailman-Users] mailman-1.1 mail loop if list owner address is undeliverable

[Todd Pfaff]

I'm using mailman-1.1.  I recently encountered a problem with a list owner
address that was undeliverable.

- some administrative message is generated that is sent to the list owner
address
- somewhere along the way, an undeliverable address is encountered and the
remote end generates a "550...Host unknown" error message which is 
returned to sender
- this is returned to the list admin address which in turn generates
another message to list owner

Are there any patches or solutions for mailman-1.1 which improve mailman's
chance of catching and stopping such a loop?  If not, is this something
that is improved in mailman-2.0?
