Okay, so why would one ever do a sender callout rather than just *always* doing a header_sender callout?

And am I missing a FAQ somewhere that explains the finer details of callouts?

Steve


As an example think about this list.  The address <[email protected]>
is never ever used to send mail (mail going to you will instead have a
sender address of <[EMAIL PROTECTED]>), so attempting a
call out verify of the address will cause the following:-
       MAIL FROM: <>
       250 OK
       RCPT TO: <[email protected]>
       550 "Recipient never sends mail so cannot cause bounces"

If you are trying to do call out verification of this address then
either:-
    1. You received a forged message in the first place (so its not my
       problem).
    2. You are extracting addresses from headers (so thats your
       problem).
