"This" refered to the action of opening a connection to an MTA and using RCPT TO commands whithout sending any mail in order to test wether some email adresses exists. "This" is defintely a Postfix feature, called "Address verification", and documented at: <http://www.postfix.org/ADDRESS_VERIFICATION_README.html> As I stated in my previous mail, I was aware that some MTAs wouldn't allow this technique to work, but since Postfix developpers spent time coding and documenting it, I guessed that there weren't so many domains doing so. That's only a guess though. Regards, -- Etienne Miret
