hi, we have
address_verify_negative_refresh_time = 30m active (root@mx2:/var/lib/postfix# postconf -n | grep verify address_verify_negative_refresh_time = 30m) but the verify behavior is strange. Jan 23 21:15:21 mx2 postfix/postscreen[Jan 25 15:31:14 mx2 postfix/smtpd[10119]: NOQUEUE: reject: RCPT from opsmail.colo.comodo.com[91.209.196.133]: 550 5.1.1 <[email protected]: Recipient address rejected: undeliverable address: host IP[IP] said: 550 5.1.1 <[email protected]: Recipient address rejected: User unknown in virtual mailbox table (in reply to RCPT TO command); from=<[email protected]> to=<[email protected] proto=ESMTP helo=<mcmail3.mcr.colo.comodo.net> Jan 25 15:31:14 mx2 postfix/smtpd[10117]: NOQUEUE: reject: RCPT from opsmail.colo.comodo.com[91.209.196.133]: 550 5.1.1 <[email protected]: Recipient address rejected: undeliverable address: host IP[IP] said: 550 5.1.1 <[email protected]: Recipient address rejected: User unknown in virtual mailbox table (in reply to RCPT TO command); from=<[email protected]> to=<[email protected] proto=ESMTP helo=<mcmail3.mcr.colo.comodo.net> Jan 25 15:31:14 mx2 postfix/smtp[10124]: 2CFE27E3A2: to=<[email protected], relay=IP[IP]:25, delay=0.25, delays=0/0.01/0.21/0.03, dsn=2.1.5, status=deliverable (250 2.1.5 Ok) I dont see a veify request at 15:31 at the remote site. why is postfix still caching verify results but report instead after client was rejected, that the address is deliverable? thank you.
