Implementing MailScanner as your Virus and Spam checker in the Domino mail environment.

It’s no surprise that i am a real open source and IBM enthusiast. Combining those two, and you can create a total new solution for the business.

What you need on your Linux Server in order to get MailScanner running?   -Postfix as your Message Agent. Can be installed from RPM -MailScanner as your Antivirus / SpamAssasin engine. Download MailScanner -MailWatch as your MailScanner WebGui. Download MailWatch

PostFix configuration

In the Postfix configuration i decided to deliver the mail on SMTP port 26 and not 25. This because i installed mailscanner on the same server as the Domino SMTP server.

vi /etc/postfix/main.cf

mail_owner = postfix

header_checks = regexp:/etc/postfix/header_checks

mydestination = $myhostname, localhost.$mydomain, localhost

local_recipient_maps =

relay_domains = $mydestination,angioni.nl

relayhost = [192.168.2.250]:26         ( this is my IBM Domino server running with SMTP listening on port 26 )

[ When you have more domains, please add them after the relay_domains input field. ]

vi /etc/postfix/header_checks

/^Received:/ HOLD

vi/etc/MailScanner/MailScanner.conf

%org-name% = TerraPro

%org-long-name% = Angioni’s SMTP server

Run As User = postfix

Run As Group = postfix

Incoming Queue Dir = /var/spool/postfix/hold

Outgoing Queue Dir = /var/spool/postfix/incoming

SpamAssassin User State Dir = /var/spool/MailScanner/spamassassin

MTA = postfix

Incoming Work Permissions = 0660

Quarantine User = root

Quarantine Group = apache

Quarantine Permissions = 0660

change owner on filesystem

chown postfix:postfix: /var/spool/postfix/incoming

chown postfix:postfix: /var/spool/postfix/quarantine

mkdir /var/spool/MailScanner/spamassassin

chown postfix:postfix /var/spool/MailScanner/spamassassin

mkdir /var/spool/mqueue

chown postfix:postfix /var/spool/mqueue

touch /var/lock/subsys/MailScanner.off
