blocking a special combination of sender and receipient

Hi there,

we are using a utm9 as mail gateway with some internal mailserver. Utm is connected with real IP and name to the world.

incoming: external mail -> utm (Spam/Antivir protection) -> mailserver
outgoing: client -> mailserver -> utm -> to the world

there is a special need to block a single internal address "content@mydomain.tld" to send to a single external address "content@remotedomain.tld".
I dont wanna change the mail system, so is there a way to block this with utm9?

Thanks for your assistance.

Dirk

Hi, Dirk, and welcome to the User BB!

You might be able to do this with a REGEX in the 'Expressions filter' on the 'Anti-Spam' tab. If this doesn't work, I can't think of how to do it in the UTM:
content@mydomain.tld.*content@remotedomain.tld

The key here is ".*" which means "any combination of any number of characters."

the recipients address can be blocked from the mailserver
You can block only the sender address in UTM like Bob said
