When a bounce occurs due to a bad email address, all my list members receive an email stating "Delivery Error, Your message was not delivered successfully." Then the original message is repeated. Can I configure mailman to only send this message to the administrator or not send the message at all? I am using version 2.14.12.cp3 inside cpanel.

First see the FAQ at <http://wiki.list.org/x/sYA9>.

That said, this should not be happening. Mailman should be sending messages with Sender: and Errors-To: headers and most importantly envelope from (Return-Path:) the LISTNAME-bounces@domain address. MTAs should be sending Delivery Status Notifications (DSNs) to the envelope from address. This should not go to the list.

Is your list anonymous. I.e. is anonymous_list on the General Options page set to Yes causing posts to be sent out From: the list address? Some broken MTAs will return DSNs to the From: address. This is wrong, but there is nothing you can do about it other than set anonymous_list to no.

Also, an MTA should not be sending a DSN From: the original recipient address or any address other than something like mailer-daemon or postmaster. These should be non-members and if you Hold non-member posts, they should not go to the list without moderator approval (Privacy options... -> Sender filters -> generic_nonmember_action = Hold).

If you post one of the actual "Delivery Error" messages here, we may be able to say more, but if there is some Mailman issue involved, it will most likely have to be dealt with by your hosting provider.
