SPAM is being received at the Kerio Mailserver hosting the domain WOLF.COM.AU
The mail appears (From: field) to be coming from users from the domain but sourced from external servers. The Return-Path: field is an external non hosted domain.
I believe I have SPF and CALER-ID configured appropriately.

My Question is: Can I filter these email based on the From Field if they come from a server not known to host the domain?

Update: your Caller-ID seems OK. This forum just stripped essential tags.

Also you must set SPF and Caller-ID to block the message, not just to increase score. That should prevent those faked emails from being delivered.

OK WIll try BLOCKING. Of note is that I use STREAMSEND for mass mailing and some users on the domain will recieve email from streamsend servers identified as being from local domain. I can work around it by using a specific domain as sender but I would prefer caller ID to allow their server also. I can't tell if the caller ID record is correct for that. Kerio caller id check does not specify that the server is allowed? Any suggestions.
