The users tell me they are not unsubscribing from the list. I've also see some emails being unsubscribed in the bounce log, that I personally sent to and know that those are valid email addresses.

Under Bounce Processing, you want Mailman to send a notification of the 
Subscribed Account being Disabled, that should include a copy of the 
last bounce that caused the subscriber to be disabled (and eventually 
unsubscribed). from that information you can start to trace the problem. 
Often it is caused by your list (or the server processing the list) to 
somehow having been placed on a blacklist.

You need to see a copy of the bounce message to see what the problem is, 
just the fact that a bounce occurred is rarely enough (It would be like 
going to the doctor and saying 'I'm sick, fix me' and not letting them 
examine you).
