comment Postfix : Only receive emails from specific domains?
Womble - Maybe you can clear this up for me; if I restrict it based on the sending address, couldn't someone just spoof an email and send it to my servers (i.e. they send me a message from jim@hotmail.com even though that's not their account)? That is why I was leaning towards using the relay hostname/ip method; since these are text messaging servers relaying me an email (i.e. you texted jim@mydomain.com from your AT&T phone) I can assume that the originator is a valid account (in this case, a cell phone customer of AT&T).

Thank you Phil for the concise response. What is the best way to discover the domains of the relay servers for the given messages?
