NAME

       MailScanner - Virus/Spam Scanner for Sendmail, Exim and Postfix

SYNOPSIS

       MailScanner [-v] [configfile]

DESCRIPTION

       MailScanner  starts  the  main MailScanner process. [configfile] should
       point   to   a    valid    MailScanner    configuration    file    (see
       MailScanner.conf(5)  for  details).  The default location for this file
       depends on the operating system.

       Linux: /etc/MailScanner/MailScanner.conf

       FreeBSD: /usr/local/etc/MailScanner/MailScanner.conf

       Other: /opt/MailScanner/etc/MailScanner.conf

       The main process  then  spawns  n  number  of  child  processes.  n  is
       configured in [configfile] with the option "Max Children". Each process
       waits for messages to appear in the  "Incoming  Queue  Dir",  processes
       these  messages and then puts them in the "Outgoing Queue Dir". You may
       need to adjust the configuration of your MTA (or the  startup  of  your
       MTA) to make it work with MailScanner.

       -v     Prints   version   information  for  Mailscanner  and  all  used
              perl-modules.

MTA SETUP

       It is important that your MTA only queues incoming mail  and  does  not
       deliver  it  automatically.  You  need  two  mail  queues (incoming and
       outgoing). Moreover you should setup two instances  of  your  MTA.  One
       that  accepts  incoming  mail  and puts it to an incoming queue and one
       that sends out mail that resides in the outgoing queue.

       A common setup for Sendmail could look like this:

       1. Verify that you already have one queue (e.g. in  /var/spool/mqueue).

       2. Create a second queue (e.g. /var/spool/mqueue.in) and apply the same
       owner/group/mode.

       3. Change your sendmail startup from

           sendmail -bd -q15m (or similar)

          to

           sendmail   -bd   -OPrivacyOptions=noetrn   -ODeliveryMode=queueonly
       -OQueueDirectory=/var/spool/mqueue.in
           sendmail -q15m

       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/configure.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
       config 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
