erroneous unsubscriptions

Hi i am the owner of a mailing list. Recently people on the list were getting unsubscribed mysteriously. I have even disabled the bounce process. A few hours ago i received 30 unsubscription notifications. This is a serious error.
Can someone please suggest how to fix this problem.
Thanks Lakshmi

As Ralf suggests, if you have access, look at Mailman's bounce log.
If users have had delivery disabled by bounce processing (a 'B' in the nomail column in the admin Membership List pages), turning off bounce processing will not prevent them from being removed after their warnings are exhausted.
If you have access to Mailman's logs and the system mail log, look at Mailman's bounce, smtp-failure and subscribe logs. If there are bounces you don't think are valid, check the system mail log too. If you don't have access to these logs, you need to be talking to the people who administer the Mailman installation you use.
