[Mailman-Users] Problem with bounced mail going to Postmaster (Postfix + MySQL)

[Eric Ward]

Mailman users:

I've recently setup Mailman 2.0.6 on RH 7.2 with Postfix 20011121snapshot using MySQL for user verification (with the virtual features).  I host a handful of different virtual mail domains on this machine, and setup a Mailman list called Natlpower for one of these virtual domains for a client.

They started using the list, and everything seems to be setup properly (that is, people received the messages, and can subscribe and unsubscribe with no problems).  However, they recently subscribed a large list of addresses.  When they sent out the first confirmation of this switch, I as postmaster for the local host received a dozen "Postmaster Copy: Undelivered Mail" messages, saying that this user is over quota, that this user doesn't exist, et cetera.  An example bounce is below, along with my Postfix configuration.

I do not want to receive these e-mails every time someone on the list sends out a message and the Postfix server gets these bounces.  However, I can't redirect all bounces to them, as most bounces won't be for their list.  I know that Mailman is supposed to handle these bounces and take action on them.

What am I supposed to do?  How can I configure Postfix to direct these bounce error messages to the "Errors-To: natlpower-admin at wearepower.org" address that appears in the Mailman message headers?  Or do I have to run a filter program to filter these bounce messages and redirect them to the 'natlpower-admin' alias?  And if the wrapper for this alias receives this bounce message, will it take the appropriate action according to its settings in the "Bounce" admin panel?

Any help would be greatly appreciated.
