Thanks Seb,
I have a feeling the previous owners of the domain redirected all e-mail
to /dev/null - hence this issue popping up now!
I doubt there's an easy way to do this - might be time to look in to
exchange event sinks!

Cheers,

Scott

This really depends on how the mailing list management software deals
with 
bounces.

As an example. in Mailman, you can configure bounce processing on a per-

list basis through the admin interface for each list. Mailman deals with

soft and hard bounces (mail temporarily undeliverable, such as mailbox 
full, and mail permanently undeliverable, such as user uknown)  by 
assigning different scores to each type. After certain score thresholds,

users will either be set to "no mail" or have their accounts invalidated

and removed. Of course, all of this is reported to the list
administrator 
so that manual intervation can occur at any point.

By default, Mailman sets nomail at a limit of 5 points, and removes 
accounts after 3 reminders have been sent to the user. Soft bounces are 
worth a half point and hard bounces are a whole point.

For reference, this is at:
