MailWatch experience can be enhanced by some optional configuration step that
With MailWatch you can manage whitelist and blacklist from the web interface.
MailScanner.conf you must set:
Is Definitely Not Spam = &SQLWhitelist Is Definitely Spam = &SQLBlacklist
Adding Postfix relay information to message detail
You can get MailWatch to watch your Postfix MTA logs and store all message relay information which is then displayed on the ‘Message Detail’ page which helps debugging and makes it easy for a Helpdesk to actually see where a message was delivered to by the MTA and what the response back was (e.g. the remote queue id etc.).
$ cp tools/Postfix_relay/mailwatch-postfix-relay /etc/cron.hourly $ chmod +x /etc/cron.hourly/mailwatch-postfix-relay $ cp tools/Postfix_relay/mailwatch_postfix_relay.php /usr/local/bin $ cp tools/Postfix_relay/mailwatch_mailscanner_relay.php /usr/local/bin $ chmod +x /usr/local/bin/mailwatch_postfix_relay.php $ chmod +x /usr/local/bin/mailwatch_mailscanner_relay.php
You will find more detail in
Exim and Sendmail
Setup Sendmail Queue Watcher
mailwatch_sendmail_queue.php script process the MTA Exim or Sendmail queue to store messages in MailWatch database and see them in the MailWatch GUI.
tools/Sendmail-Exim_queue/mailwatch_sendmail_queue.php file in
/usr/local/bin and make it executable:
$ cp tools/Sendmail-Exim_queue/mailwatch_sendmail_queue.php /usr/local/bin $ chmod +x /usr/local/bin/mailwatch_sendmail_queue.php $ crontab -e # Run each minute 0-59 * * * * /usr/local/bin/mailwatch_sendmail_queue.php
mailwatch_sendmail_queue.php re-creates all entries on each run, so for busy sites you will probably want to change this to run every 5 minutes or greater.
Setup the Sendmail Relay Log watcher
You can get MailWatch to watch your Sendmail MTA logs and store all message relay information which is then displayed on the ‘Message Detail’ page which helps debugging and makes it easy for a Helpdesk to actually see where a message was delivered to by the MTA and what the response back was (e.g. the remote queue id etc.).
# cp tools/Sendmail_relay/mailwatch_sendmail_relay.php /usr/local/bin/. # cp tools/Sendmail_relay/mailwatch-sendmail-relay /etc/init.d/. # chmod +x /usr/local/bin/mailwatch_sendmail_relay.php # chmod +x /etc/init.d/mailwatch-sendmail-relay # /etc/init.d/mailwatch-sendmail-relay start # update-rc.d mailwatch-sendmail-relay defaults
For others Linux distributions, please change according to.
mailwatch_sendmail_relay.php run with ‘root’ user. Change user to your webserver or Sendmail MTA user (check right one on /var/log/mail.log).
MailScanner Rule Editor
Make sure MSRE (MailScanner Rule Editor) is enabled in MailWatch’s
<?php // Enable MailScanner Rule Editor define('MSRE', true); define('MSRE_RELOAD_INTERVAL', 5); define('MSRE_RULESET_DIR', '/etc/MailScanner/rules');
Change file permissions so that we can update the rules, and change group and rules directory locations as appropriate
$ chgrp -R www-data /etc/MailScanner/rules $ chmod g+rwxs /etc/MailScanner/rules $ chmod g+rw /etc/MailScanner/rules/*.rules

LDAP directory for user management
You can use a LDAP directory to authenticate users. Setting
conf.php will enable the backend and will connect to the ldap server
LDAP_HOST on the port
LDAP_PORT and binds to it by using
LDAP_PASS as credentials. That user must have read access to the users login name and attributes that you are using for the filter.
MailWatch will search users that are allowed to use it by using
LDAP_DN as search base and
LDAP_FILTER to filter the ldap entries to get the matching users login name. In the
LDAP_FILTER you can use
%s as replacement for the users login name that he entered on the login page of MailWatch.
From this search result MailWatch uses the ldap attribute defined by
LDAP_USERNAME_FIELD as login name to bind to the server for authentication.
This login name can be extended by a prefix (
LDAP_BIND_PREFIX) and suffix (
The user then is authenticated with his password and this aggregated login name. Additionally you can define the ldap attribute containing the users mail address with
LDAP_EMAIL_FIELD which will be used to only show the user mails that are related to his mail address as recipient or sender.
Settings for Active Directory:
define('LDAP_FILTER', 'mail=%s'); define('LDAP_EMAIL_FIELD', 'mail'); define('LDAP_USERNAME_FIELD', 'userprincipalname');
Example for OpenLDAP:
define('LDAP_FILTER', 'mail=%s'); define('LDAP_EMAIL_FIELD', 'mail'); define('LDAP_USERNAME_FIELD', 'cn'); define('LDAP_BIND_PREFIX', 'cn='); define('LDAP_BIND_SUFFIX', ',dc=example,dc=com');
Web interface skinning
From 1.2.1 it is possible to add
skin.css file to
/opt/mailwatch/mailscanner directory with your custom css rules.
This file will not be overwritten by git upgrade, but remember to back it up if upgrading with zip method.
