[MM3-users] bounce handling in mm3 available?

Hi,

what happens with bounce-mails that are processed by mailmans postfix instance?

Jan 24 10:46:03 l01 postfix/lmtp[8432]: DF4AE600623: to=<company-newsletter-bounces@lists.company.tld>, relay=127.0.0.1[127.0.0.1]:8024, delay=0.03, delays=0.01/0.01/0/0.01, dsn=2.0.0, status=sent (250 Ok)

But the list-owner does not get any notification, nor do i see any bounce-information in the pistorious-gui.

How are the bounce-mails handled?

Thank you.

Stefan
