Wrench Emails issue

Dear all,
I am facing an issue in my data Center environment related to mails being generated by users on my machines.

Let me walk you through the issue one by one.

Each system (100+ servers in my DC) has a user sysmon on it that sends mails to a specific Email ID. The user runs scripts related to system monitoring i.e. scripts monitoring disk space , system health etc.

Example name of 2 systems are mercury0 & mercury1

The scripts work fine and send Emails to the ID given.

The issue arises when the /var/spool/mqueue directory on my MTA Relay host servers starts to increase with Emails being stuck in them.

Those emails are addressed to the system's own users.
Mercury0 is sending an Email to itself using sysmon ID.

Example of two mail outputs found on my MTA Relay host servers are below:

I did did the following on the /var/spool/mqueue directory on one of my MTA Relay host servers:

Code:
sudo cat * | grep sysmon | grep mercury0

Code:
H??To: sysmon@mercury0.domain.com

H??To: sysmon@mercury1.domain.com

How can I make sure that such mails do not pile up in the /var/spool/mqueue directory of my MTA Relay host servers?
Is there a way to make sure such mails being addressed to a systems own ID be forwarded to another Email ID but hte best option would be to simply discard them.


P.S. I have placed the IP address of MTA Host servers in the submit.cf file on all client machines.

Regards

uudemon(4)						     Kernel Interfaces Manual							uudemon(4)

NAME
uudemon.admin, uudemon.cleanu, uudemon.hour, uudemon.poll - Administrative shell scripts for polling remote systems, cleaning up spool directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons SYNOPSIS
These shell scripts reside in the following directory: /usr/lib/uucp DESCRIPTION
All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the scripts, remove the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file. This script reports status to the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID (uucpa) or root. This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com- mand is run with the following parameters: -C7, -D7, X2, -o2, -W1. This script runs the uusched and uuxqt daemons in the background. This script polls the systems listed in the /usr/lib/uucp/Poll file. The uudemon.poll script should be scheduled before the uudemon.hour script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script. FILES
Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files. Contains the uucp file. RELATED INFORMATION
Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1) Files: /usr/lib/uucp delim off uudemon(4)
