Verifying sender's address in Postfix
Hello,
I've found out, that there is a daemon called "verify" for the Postfix, which takes care of checking, whether the sender's email address actually exists. It processes the directives "smtpd_sender_restrictions = reject_unverified_sender" etc. Unfortunately, it's not included with any version of Postfix. Could you, please, provide me with a address, where I can download this daemon?
Thank you.
