In the past, I have had messages coming in (via port 25) claiming to be 
Helpdesk, Personnel, etc

So I had incorporated into my sender_access file the line:-
cidercounty.org.uk           permit_sasl_authenticated, reject

Do you think something like this would be beneficial WRT the smuggling problem?
