It is our recommendation to not use this module. If you need a monitoring solution you may want to look for an off-site option. Our newer servers are not provisioned with watchdog installed. If you have an older server and would like to remove watchdog you can run the following command via ssh as root to remove the watchdog package.

rpm -e psa-watchdog

Turning off SpamAssassin may significantly increase the amount of spam that your email accounts receive. You will have to decide for yourself if this is a trade-off that you are comfortable with. To help further prevent spam we strongly suggest disabling any “catch-all” email addresses and enabling “reject emails to non-existent users” in the Mail section under Clients >> Domains >> Mail in Plesk.

Type the following command in your SSH session:

/etc/init.d/psa-spamassassin stop

To disable it permanently, run the following command by typing

chmod 644 /etc/init.d/psa-spamassassin

You can always add it back by changing 644 to 755.

Received: (qmail 30501 invoked by uid 10077); 3 Dec 2009 21:47:42 -0500
Date: 3 Dec 2009 21:47:42 -0500
Message-ID: <20091204024742.30498.qmail@hostserver.com>
To: email@domain.com
Subject: This is a test.
MIME-Version: 1.0
Content-type: text/html; charset=iso-8859-1
From: <user@domain.com>

It says its invoked by uid 10077 which corresponds to the account on the /etc/password file:

-bash-3.2# more /etc/passwd | grep 10077
username:x:10077:2522::/var/www/vhosts/domain.com:/bin/false

That rule will accept Postini’s block. Then, to block the rest of the email:

• Choose Add Custom Rule
• Enter in a rule name
• Choose incoming
• Choose DENY
• Enter in port 25 and press ADD
• Leave the network space blank
• Press OK

It is important that you have the rules in this order, otherwise all email will be denied. Ensure that the ALLOW is above the DENY in the display list when you are done, then commit the changes.

The table uses the field ‘dom_id’ as a reference to the owner. Look in the ‘domains’ table to find the ‘id’ of the domain you are using and the one you wish to move to then make the change in the ‘data_bases” table.

Once changed, you will see the database listed under the new domain in Plesk. You can then add/change usernames and passwords through Plesk as normal.

You can do all the above through the command interface (SSH) or you can do it the easy way with a tool like phpMyAdmin installed.

/parallels_plesk_panel_installation_directory/admin/sbin/websrvmng --reconfigure-vhost  --vhost-name=

On Centos 5

/usr/local/psa/admin/sbin/websrvmng -u --vhost-name=domain.com

In Plesk 10

/usr/local/psa/admin/sbin/httpdmng --reconfigure-domain domain.com

tail /usr/local/psa/var/log/maillog -n10000 | grep "user@example.com"

Notes:

Better to tail than cat (in case its a big log)

-n10000 is going back 10000 lines

Add -f if you want to see a live feed of the log

tail -f /usr/local/psa/var/log/maillog | grep "user@example.com"
