Mailscanner has several configuration options i will only dwell on those that are needed to get the system working. To further customize the system please read the mailscanner documentation or look at the sample configuration files that i have provided.

• Please edit the following configuration variables in /etc/MailScanner/MailScanner.conf

Run As User = exim
Run As Group = exim
Incoming Queue Dir = /var/spool/exim.in/input
Outgoing Queue Dir = /var/spool/exim/input
MTA = exim
Sendmail = /usr/sbin/exim -C /etc/exim/exim.conf
Sendmail2 = /usr/sbin/exim -C /etc/exim/exim_out.conf

• Set permissions

# chown exim.exim -R /var/spool/MailScanner/incoming
# mkdir -p /var/spool/exim.in/{input,msglog,scan,db}
# chown exim.exim /var/spool/exim.in/{input,msglog,scan,db}

• If you have a second virus scanner set

Virus Scanning = yes
Virus Scanners = "name of virus scanner"

We will be using SQL(mysql) based whitelisting and blacklisting to easily integrate with the mailwatch front end to allow users to whitelist and blacklist senders from within the web interface.

• Edit the mailscanner configuration file and add

Is Definitely Not Spam = &SQLWhitelist
Is Definitely Spam = &SQLBlacklist
Ignore Spam Whitelist If Recipients Exceed = 20

• Edit the file /usr/lib/MailScanner/MailScanner/CustomFunctions/SQLBlackWhiteList.pm

sub CreateList {
  my($type, $BlackWhite) = @_;
  my($dbh, $sth, $sql, $to_address, $from_address, $count);
  my($db_name) = 'mailscanner';
  my($db_host) = 'localhost';
  my($db_user) = 'mailwatch';
  my($db_pass) = 'password';

• Edit the mailscanner configuration file and add

Always Looked Up Last = &MailWatchLogging

• Edit the file /usr/lib/MailScanner/MailScanner/CustomFunctions/MailWatch.pm

my($db_name) = 'mailscanner';
my($db_host) = 'localhost';
my($db_user) = 'mailwatch';
my($db_pass) = 'password';
