Can anyone point me to a How-To or any other documentation to explain
how to implement the above?
In simple terms, what I want to do for the domain mydomain.com is to
check incoming (external) mail and reject it if it purports to come from
I suppose the alternative is to reject incoming mail claiming to be from
mydomain.com that is not being sent from the mailservers of mydomain.com.
Hope this makes sense.
Thanks and Rgds
