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).
