Every day I found message like that in my postfix log.
I can't understand who is blocking message from MAILER-DAEMON
Oct 08 12:00:04 securemail <info> postfix/smtpd[14358]: 884025A4004:
reject: END-OF-MESSAGE from localhost[127.0.0.1]: 450 4.7.1
<END-OF-MESSAGE>: End-of-data rejected: Access denied;
from=<MAILER-DAEMON> to=<[email protected]> proto=ESMTP
helo=<securemail.realt.it>
The message blocked is a quota warning to a user.
Is it Possible it is policyd?
Have I to add MAILER-DAEMON somewere in policyd config?

In Var/log/mail.* I didn't find nothing about it.
I found this message in policyd.log for every mail sent from MAILER-DAEMON.

It seems that "mail from: MAILER-DAMEON" is not accepted by policyd.
