Hi,
I have to update my server from Debian 12 to Debain 13. To minimize the surprises I am testing the process on a virtual machine running forky.
The server is needed to handle mail with postfix/dovecot. I managed to get dovecot running with the changed configuration. Postfix 3.10 is the problem now:
It fills the mail queue with thousands of mails from double-bounce@localdomain to postmaster@localdomain.localdomain and from MAILER-DAEMON to double-bounce@localdomain-localdomain
It seems to occur whenever postmaster is not able to deliver the mail -- it should bounce to the sender but it doesn't. System is configured to use an external relay host.
I took configuration from my working server with postfix 3.7.11
Delivery is (should be) done by procmail to local maildir.
From master.cf:Where should I start searching for the root of the problems?
