Problem w/ return email -- Domain still displays!

Currently when sending an email via Notes agent, the email format is something like:

“sender@notesdomain.companyname.com”

What i want it to say is:

“sender@companyname.com”

The notes domain is not a case of domain/domain, it’s just the domain name…but I can’t figure out where to remove this.

In my Global Domain document, I have the following settings:

Local Primary Internet Domain: companyname.com

Domino domain(s) included: None

I can’t figure out why it’s still adding the domain.
