This means that the subscriber's e-mail address is bouncing. In other 
words, the addresses are returning either permanent or transient 
errors (unknown user, mailbox full, etc.)

Mailman keeps track of these errors and disables delivery to these 
addresses until the problem is resolved.

Go to the list admin page and select Bounce Processing. There is a 
description on that page of how this works and you can configure when 
or if it is triggered. You can shut off the bounce processing, but 
this is not recommended for a number of reasons.
