Exim + Mailscanner on freeBSD

[Marco Obaid]

Hi,

The FreeBSD port that I downloaded from MS website (which I recommend you use
since it is the latest), installs a script "mta.sh" under /usr/local/etc/rc.d/
which has the correct parameters. I don't use Exim but I just got through
installing MS on FreeBSD with sendmail and came across Exim setup.

      A similar setup for Exim could look like this:

       1. Create two queues (e.g. /var/spool/exim.in and  /var/spool/exim.out)
       with  appropriate  owner/group/mode  (e.g.  owner=mailnull, group=mail,
       mode=750).

       2. Create two  exim  configurations  (e.g.  /usr/local/etc/exim/config-
       ure.in, /usr/local/etc/exim/configure.out).

       3. Make sure that the incoming exim configuration only queues mails and
       never delivers mail itself. This can be achieved by using the Exim con-
       fig option "queue_only = true" and/or a special router definition (Exim
       4 syntax):

           defer_router:
           driver = manualroute
           self = defer
           transport = remote_smtp
           route_list = *  127.0.0.1  byname
           verify = false

       4. Start two exim instances:

           exim -C /usr/local/etc/exim/configure.in
           exim -C /usr/local/etc/exim/configure.out



Here is a copy of the script:
