To help stop spoofing I would like to add an EXTERNAL EMAIL warning message on the subject line or body of the email.

I have already set up a Rule in Message Filters Incoming that has
FROM --> DOES NOT CONTAIN ---> (MYDOMAIN.COM)
add [WARNING - External email] ${subject}

But is still adding it to all emails, replies, and forward to our users

[WARNING - External email] Fwd: [WARNING - External email] Fwd: [WARNING - External email] RE: P4800650 expedite
Fwd: [WARNING - External email] Fwd: [WARNING - External email] RE: P4800650 expedite

How can I configure this?

While I can't help you with the rules, I have a suggestion: You can avoid external senders from spoofing your own email domain in the sender address with some controls in Kerio Connect. This will block the emails, so no need to flag them in the subject:

Go to Configuration > Domains > yourmaildomain.com

Click on the Security tab

Tick "Reject messages with spoofed sender identity"

Click "OK"

That will avoid these messages from arriving at the users.

In addition you can also set up SPF to prevent spammers from using your domain as a sender address to send mail to anyone in the world.
