[Mailman-Users] bouncing process does not return messages on user unknown

Thank you very much - indeed I checked and all the settings for bound process are OK.
I checked also the maillog file for that particular mailing list and I saw different values for status:
Stat : Service unavailable
Stat : Deferred
There are several external relay servers with verify=FAIL
Or Recipient address rejected: Greylisted

How mailman gets this status values ( as hard in bounce process ) , should it send back error messages to the owner / sender  .
I'm sorry to disturb you with my questions but I'm very confused - how the mailing list gets back the errors and in what cases.

Again thank you

See the list's web admin Bounce processing page. Also see Mailman's 'bounce' log.

Bounces are returned to Mailman. If the list's bounce_processing setting is No, they are ignored. If Yes, they are handled according to the remaining settings. List owners are not notified until a members bounce score reaches bounce_score_threshold and the member's delivery is disabled, and then only if bounce_notify_owner_on_disable is Yes
Beginning in 2.1.19, a list admin can request notification any time a member's score is incremented.

These admin notices contain a copy of the triggering bounce.
