Re: [FW-1] Blocking Mailing-List



We had a problem where mail from *@yahoogroups.com was getting stuck in our mail system.  It turned out to be related to the large number of mailsystem hops many yahoogroup mailings take.

Our mail server had a limit set on the maximum number of mail hops increasing this solved the problem.

I'm not sure if this is your problem, but to answer your question.

You need to set up an smtp resource with

mail server : Your destination mail server IP address
match tab -> sender: *@yahoogroups.com

Leave the recipient field empty unless you want to restrict the blocking to a specific one of your domains.  In this case set the recipient to *@yourdomain.com

Then use this resource in a rule as follows

Source : Any
Destination : Your mail server
Service : the smtp resource defined above
Action : Drop
Track : Long

Make sure this goes above your rule to accept all other SMTP going to your mail server.

Hope this helps.

Regards,
Paul.
