Yes, but I'm talking about having spamassassin do the recognizing before it reaches the humans. OK, that means some training for what each trusted subscriber's message usually looks like. I have an idea: let's discuss this complicated question at some other time. >> OK, I suppose that would be caught by SPF rules etc., if bob likes SPF.

All I know is that I don't use SPF anymore for my domain as there are just too many problems... e.g., forwarded messages.
