Package: postfix Version: 2.10.0-1 Severity: important I use TLS keys to authenticate and allow relaying of mail from trusted clients, using relay_clientcerts.
Upgrading broke it: Mar 9 10:23:26 wren postfix/smtpd[14341]: connect from dialup-4.154.6.204.Dial1.Atlanta1.Level3.net[4.154.6.204] Mar 9 10:23:29 wren postfix/smtpd[14341]: Trusted TLS connection established from dialup-4.154.6.204.dial1.atlanta1.level3.net[4.154.6.204]: TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits) Mar 9 10:23:31 wren postfix/smtpd[14341]: NOQUEUE: reject: RCPT from dialup-4.154.6.204.Dial1.Atlanta1.Level3.net[4.154.6.204]: 554 5.7.1 <jo...@debian.org>: Relay access denied; from=<j...@gnu.kitenet.net> to=<jo...@debian.org> proto=ESMTP helo=<gnu.kitenet.net> Mar 9 10:23:32 wren postfix/smtpd[14341]: disconnect from dialup-4.154.6.204.Dial1.Atlanta1.Level3.net[4.154.6.204] I downgraded back to 2.9.3-2.1 and relaying once again works.
