Running MIMEDefang as non-root

------------------------------

It is required to run MIMEDefang and the multiplexor as non-root.  You

should create a dedicated user for MIMEDefang.  In the examples, I'll

call this user "defang".

To run as defang:

1) Supply the "-U defang" option to mimedefang.

2) Supply the "-U defang" option to mimedefang-multiplexor.

3) Make the spool and quarantine directories owned by defang, with mode 700.

4) If you are using statistics logging in the default /var/log/mimedefang

directory, make that directory owned by defang with mode 755 or 700, depending

on your tastes.

5) You *MUST* create the socket(s) and pid file(s) in the spool directory.

As of MIMEDefang 2.13, this is the default.  You may have to edit your

sendmail.cf or sendmail.mc file to use /var/spool/MIMEDefang instead of

/var/run as the directory containing the milter socket.
