Hi, I have:
# postconf |grep unverified_recipient_reject_ unverified_recipient_reject_code = 550 unverified_recipient_reject_reason = Unknown recipient address Yet, postfix is still rejecting with: May 20 08:38:27 mx10 postfix/smtpd[8934]: NOQUEUE: reject: RCPT from host.com[x.x.x.x]: 450 4.1.1 <recei...@dom.com>: Recipient address rejected: unverified address: Unknown recipient address; from=<sen...@dom2.com> to=<recei...@dom.com> proto=ESMTP helo=<host.com> What am I missing? I don't understand why it's rejecting with 450 instead of 550 ? Thanks
