Trying out the new \c feature of smtpd_reject_footer and getting unexpected behavior. While everything looks normal in the logs, the sending client gets a timeout/lost connection.
Oh, found a workaround. Add \n at the end of smtpd_reject_footer. mail_version = 2.10-20120404 # main.cf smtpd_reject_footer = \cContact postmas...@example.org for assistance. Include this data: servertime=($localtime) client=([$client_address]:$client_port) server=($server_name) Logs look normal on the receiving end until the timeout: Apr 7 15:01:30 mgate3 postfix/smtpd[25040]: connect from mailgate.example.org[192.168.70.34] to smtpd Apr 7 15:01:30 mgate3 postfix/smtpd[25040]: Anonymous TLS connection established from mailgate.example.org[192.168.70.34]: TL Sv1 with cipher DHE-RSA-CAMELLIA256-SHA (256/256 bits) Apr 7 15:01:30 mgate3 postfix/smtpd[25040]: NOQUEUE: reject: RCPT from mailgate.example.org[192.168.70.34]: 550 5.1.1 <goober f...@mgate3.example.org>: Recipient address rejected: User unknown in local recipient table; from=<r...@mgate2.example.org> to=< gooberf...@mgate3.example.org> proto=ESMTP helo=<mailgate.example.org> Apr 7 15:02:30 mgate3 postfix/smtpd[25040]: timeout after DATA from mailgate.example.org[192.168.70.34] Apr 7 15:02:30 mgate3 postfix/smtpd[25040]: disconnect from mailgate.example.org[192.168.70.34] Sending client: Apr 7 15:01:30 mgate2 postfix/smtp[80066]: Trusted TLS connection established to mgate3.example.org[192.168.70.43]:25: TLSv1 with cipher DHE-RSA-CAMELLIA256-SHA (256/256 bits) Apr 7 15:02:30 mgate2 postfix/smtp[80066]: 3VQ7vZ0Txvz190bw: to=<gooberf...@mgate3.example.org>, relay=mgate3.example.org[192.1 68.70.43]:25, delay=61, delays=0.07/0.05/0.28/60, dsn=4.4.2, status=deferred (lost connection with mgate3.example.org[192.168. 70.43] while sending RCPT TO) -- Noel Jones
