Hello,
I have a question regarding configuring submission with Postfix.
I am dusting off a configuration for a server that has been functioning
well for the past three years. When I set up submission, I used the
example from Digital Ocean here:
https://www.digitalocean.com/community/tutorials/how-to-set-up-a-postfix-e-mail-server-with-dovecot
This article was helpful, but it is:
1. From November 14, 2013
2. Refers to Postfix 2.9.6
In particular, it lists one parameter that I was uncertain about:
/etc/postfix/master.cf
submission inet n - y - - smtpd
-o milter_macro_daemon_name=ORIGINATING
. . .
I checked: man 5 postconf and milter_macro_daemon_name states:
The {daemon_name} macro value for Milter (mail filter) applications.
See MILTER_README for a list of available macro names and their
meanings.
I consulted MILTER_README at: http://www.postfix.org/MILTER_README.html
but I am still uncertain why "ORIGINATING" is being used for the
Sendmail macro of {daemon_name}.
I use the following milters with submission:
-o
smtpd_milters=unix:/var/run/opendkim/opendkim.sock,unix:/var/run/clamav/clamav-milter.sock
... for DKIM signing (OpenDKIM), and checking for viruses from infected
submitters (ClamAV).
My questions are:
1. Why was the magic value of "ORIGINATING" used in the Digital
Ocean example ?
2. Can I allow the default value of: milter_macro_daemon_name to
be used _WITHOUT_ affecting OpenDKIM and ClamAV ?
Thanks,
- J
