For some time, Mailman has not allowed subscription of an address with
whitespace or 'invalid' characters, but if you have command line access,

bin/list_members -i <listname>

will print any addresses with invalid characters although the invalid
characters ma not themselves be displayed.

Actually, the bounce log shows the list, user and score for each bounce
from a list member address.

In addition, you can see the user's current bounce score if > 0 by
clicking the user's address in the Membership Management...-> Membership
List page to go to her user options page where that info is displayed.

Also, there is a withlist script at
<http://www.msapiro.net/scripts/get_bounce_info.py> which will display
bounce info for members that have any.

The actual DSN is not available except that in the case where
bounce_notify_owner_on_disable is Yes, the one DSN that triggers the
disable is included in the notice to the owner.
