Hello,
I have just been pointed to the SPF information, which is saying that "It is RECOMMENDED that SMTP receivers record the result of SPF processing in the message header."
See: http://www.openspf.org/RFC_4408#header-field
Is it possible to impliment this with Content filtering? I couldnt see how to do it if it is possible! also is there a possiblity that this would be included in AMS 3 (or beyond!)?
Thanks very much
Ian
