I'm not sure how to do that. I'm new to postfix. Since I used iRedMail
scrip to set this up I'm having to reconfigure everything as I go. It
worked fine on our other mail servers but this one just has too much.

I think I'm going to start over and research how to build a minimal, fast,
small footprint smtp/pop mail server for basic send and receive with speed
and stability being the main focus.

use a specific IP:port to submit these messages and disable filtering
for the corresponding smtpd (-o content_filter=)
you can configure this smtpd to only accept mail from specific IPs.
