As already mentioned by others you need to look at sender_verify, but I'm
wondering if you have a similar setup to what we have at our site.
All our mail passes a number of mail relay machines, with email only
being sent to the central mail server if it is destined for a local
recipient. Obviously we want to have the mail relays check for the above
type of problem. We have a router with verify_only and self=local
set. Mail from local senders or to local recipients are passed through the
directors (verify_only set on them, no_more on the last director) to do
some various checks to see if the local sender/recipient is valid.
Rgds.,
Nick.
