I am going in circles between postfix issues and mailman. However, before I continue with postfix debugging I want to resolve this first as it may be related for all I know. I'm getting this error in the postfix mail log:
2026-02-01T11:00:10.106626-05:00 dap002 postfix/local[113730]: 01623500076: to=<mailman@myhost.localdomain>, orig_to=<mailman>, relay=local, delay=0.16, de lays=0.11/0.01/0/0.04, dsn=5.2.0, status=bounced (cannot update mailbox /var/mail/mailman for user mailman. cannot open file: Permission denied)
I'm not sure why mailman is trying to write to that file but it is owned by root:mail. It is obvious why permission is denied to mailman. Is that directory really part of mailman3 and if so what should ownership and permissions be? If not then why is mailman trying to write to it? That path does not appear in any of the files in /etc/mailman3.
Postfix is trying to deliver mail to a mailman@... address to the local
user mailman. The user:group of the file /var/lib/mailman should be
mailman:mail. if you sudo chown mailman /var/lib/mailman, those
messages will be delivered to that mailbox and you can see what they are.
What are all the log messages from grep 01623500076 /var/log/mail.log?
Possibly you have set
site_owner: mailman
in mailman.cfg which would cause Mailman to send various notices to the
local mailman user.
