Hello, I have observed that OpenSMTPD hangs when you try to deliver a message with an empty body (i.e. when the dot appears on the line directly after the headers).
This can be observed by a simple telnet to OpenSMTPD. ========== $ telnet localhost 25 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. 220 mars.pole.net.nz ESMTP OpenSMTPD HELO localhost 250 mars.pole.net.nz Hello localhost [127.0.0.1], pleased to meet you MAIL FROM:<ja...@pole.net.nz> 250 2.0.0: Ok RCPT TO:<ja...@pole.net.nz> 250 2.1.5 Destination address valid: Recipient ok DATA 354 Enter mail, end with "." on a line by itself From: James Pole <ja...@pole.net.nz> To: James Pole <ja...@pole.net.nz> Subject: Test . ========== This occurs with both the smtpd in the OpenBSD 6.0 base system as well as the smtpd from pkg on FreeBSD 10.3-RELEASE. Sendmail in the FreeBSD base system does not exhibit this behaviour. I have not yet tested with other MTAs. These are the details for the OpenBSD machine I have found this behaviour on: ========== $ uname -a OpenBSD mars.pole.net.nz 6.0 GENERIC#0 amd64 $ smtpd -h version: OpenSMTPD 6.0.0 usage: smtpd [-dhnv] [-D macro=value] [-f file] [-P system] [-T trace] $ cat /etc/mail/smtpd.conf table aliases file:/etc/mail/aliases pki mars.pole.net.nz certificate "/etc/ssl/acme/fullchain.pem" pki mars.pole.net.nz key "/etc/ssl/acme/private/privkey.pem" listen on lo0 listen on lo0 port 10026 tag spampd listen on egress port 25 tls pki mars.pole.net.nz listen on egress port 587 tls-require pki mars.pole.net.nz auth mask-source accept from local for local alias <aliases> deliver to lmtp "/var/dovecot/lmtp" accept tagged spampd for any alias <aliases> deliver to lmtp "/var/dovecot/lmtp" accept from any for domain "pole.net.nz" relay via smtp://127.0.0.1:10025 accept from local for any relay $ ========== Just wanted to check with misc@ for ideas on whether this is a bug with OpenSMTPD before I forward to bugs@.
