On my new MM3 that I just installed, I testing unsubscribe user from mailing list. User received email for the unsubscribe in subject line as 'You have been unsubscribed from the Test1 mailing list' with email address 'test1-bounces@domain'.
Do you mean the notification email from the list is From test1-bounces@domain? Are you sure it is from "test1-bounces@domain"? It should be from "test1-owner@domain". Most notifications to users come from the "LIST-owner" address.
Mailman uses the "LIST-bounces" address as the "envelope sender" address, which is used by mail servers as the return address for undeliverable mail. Although the envelope sender address is not visible in most mail clients, maybe that is what you are seeing instead of, or in addition to, the From address that clients usually display?
It should receive from test1-unsubscribe@domain instead. Where should I look into this? or configure it.
It should not be from "test1-unsubscribe". That will result in messages to the user that confuse most people, if they happen to reply to it.
There is no configuration option. The source addresses that Mailman uses for automatically-created emails have been tested over decades. Changing them can cause a lot of confusion. You would have to patch the Python code.
