X-Security headers in emails

Any email received through my server gets some headers added to the email, can someone explain why they show up and what to do to get rid of them?

I take it it's something to do with the fact I have MailScan enabled for the user?

Code:

X-Security: message sanitized on xxx.abc.com
	See http://www.impsec.org/email-tools/sanitizer-intro.html
	for details. $Revision: 1.151 $Date: 2006-01-20 07:29:24-08 
X-Security: The postmaster has not enabled quarantine of poisoned messages.

 

Thanks, is there anyway to "enable quarantine of poisoned messages"?

Or do I just have to live with these messages?

 

Take a look at http://www.impsec.org/email-tools/procmail-security.html and search for quarantine.

 

Thanks, have found this page: http://www.impsec.org/email-tools/sanitizer-configuration.html

However it goes on to say about editing /etc/procmailrc which I don't have.

Do I create this or has ISPConfig already done that and placed it somewhere else?

 

/etc/procmailrc is the global procmailrc file that would be valid for all users.
ISPconfig is creating individual procmail recipes which you can find in each user's homedir.
