Subject:	sender address verification vs. script-generated messages?

Hi folks! I've got some PHP scripts running on a web server that
periodically generate messages, some of which go to users on our
local mail servers. I've just enabled sender address verification
for our local domains, and it's zapping those messages because they
come from "generic" (and undeliverable) From: addresses.

Is there some way to "whitelist" (for lack of a better term) those
messages? If not, what's the accepted "clean" way of dealing with this?

Thanks,
-Dave
