Is there a way to tell spam assassin to avoid any processing of local emails?

Greetings:

Is there a way to tell Spam Assassin (SpamAssassin 3.1.7) to skip processing
emails sent from our network (public IP addresses are involved)?

I do have TrustedNeworks set up, but I don't know if there is another
variable that must also be set up.

Thank you.

No.  SpamAssassin scans anything sent to it.  The only way to skip processing
is to not send the message to SA in the first place.


(note: this will change in 3.2, but it's not released yet...)

The best way is to avoid passing such messages to SA at all in the
first place.

Public IPs being involved is not that big a hurdle. What makes it
difficult is allowing for roaming or dynamic-IP users.

Basically you need to look at:

(1) What is your MTA? Sendmail? Postfix? EXIM?

(2) How is your MTA passing messages to SA? Procmail? Milter? Some
other mechanism?

(3) How do you identify your locally-originated messages? By IP ranges
(private or public)? By authenticated user? Both? What does the
Received header that *your* MTA adds to a locally-originated message
look like?

(4) How do you tell your MTA to recognize those messages? Source IPs?
Substrings from the Received: header?

(5) Once you've told your MTA how to recognize them, how do you tell
it to bypass SA for those messages?
