Sorry if this has been asked/answered before. I've searched and searched and
found no consistent, complete answers.
What are the steps to configure MIMEDefang and Postix to share a socket?
Here's what I tried:
Option 1: Use inet socket
------------------------------------------------
/etc/default/mimedefang:
SOCKET=inet:8899@localhost
/etc/postfix/main.cf
smtpd_milters = inet:localhost:8899
This works for Ubuntu 14.04/MIMEDefang 2.73.
But it fails with Ubuntu 16.04/MIMEDefang 2.78. If Postfix is already running,
and MIMEDefang is restarted, I get the following in /var/log/mail.err:
mimedefang[27605]: MIMEDefang-2.78: Unable to bind to port
inet:8899@localhost: Address already in use
mimedefang[27605]: MIMEDefang-2.78: Unable to create listening socket on
conn inet:8899@localhost
Option 2: Use unix socket in MIMEDefang directory
--------------------------------------------------
/etc/default/mimedefang:
<leave default SOCKET line (/var/spool/MIMEDefang/mimedefang.sock)>
MD_ALLOW_GROUP_ACCESS=yes
add user "postfix" to group "defang"
usermod -a -G defang postfix
/etc/postfix/main.cf:
smtpd_milters=unix:/var/spool/MIMEDefang/mimedefang.sock
This fails, presumably because Postfix is chroot'ed and can't access anything
outside it's chroot directory (/var/spool/postfix). In /var/log/mail.err:
postfix/smtpd[31110]: warning: connect to Milter service
unix:/var/spool/MIMEDefang/mimedefang.sock: No such file or directory
Option 3: Use unix socket in Postfix chroot jail
-------------------------------------------------
I suppose I could configure /etc/default/mimedefang:SOCKET to point to a file
in /var/spool/postfix/private, where the other sockets are located. But that
directory is owned by postfix, group=root, permissions 0700. So I don't know
how mimedefang could write to it.
So, I'm stuck.
Any help would be appreciated.
