Ok, I'm either dense, or I've been staring at this too long.  If I set 
'sender_verify = true', how can I set 'sender_reject' so that From 
headers from only outside the local domain are rejected?  I want to 
relay 'example.com' email coming out from the local network, but prevent 
email with forged From headers containing 'example.com' coming from the 
Internet and being relayed.  There are no local accounts on the gateway, 
everything is relayed.

Thanks,

Ken
