Hi, Dovecot 2.3.1 (8e2f634). When using submission one client of mine can not send messages. Directly sending through exim works. Seems that dovecot is too picky or follow the RFC too precise here to be compatible. Here is the debug log (note the space between ?From:" and "<user2 at host.com>?): Apr 6 12:02:08 mail dovecot: submission(user at host.com)<14972><ko4tJitpt9JYSSSC>: Debug: smtp-server: conn 22.73.xx.144:53943 [0]: Received new command: MAIL From: <user at host.com> Apr 6 12:02:08 mail dovecot: submission(user at host.com)<14972><ko4tJitpt9JYSSSC>: Debug: smtp-server: conn 22.73.xx.144:53943 [0]: command MAIL; 501 reply: Submitted Apr 6 12:02:08 mail dovecot: submission(user at host.com)<14972><ko4tJitpt9JYSSSC>: Debug: smtp-server: conn 22.73.xx.144:53943 [0]: command MAIL: Ready to reply Apr 6 12:02:08 mail dovecot: submission(user at host.com)<14972><ko4tJitpt9JYSSSC>: Debug: smtp-server: conn 22.73.xx.144:53943 [0]: Trigger output Apr 6 12:02:08 mail dovecot: submission(user at host.com)<14972><ko4tJitpt9JYSSSC>: Debug: smtp-server: conn 22.73.xx.144:53943 [0]: Timeout stop Apr 6 12:02:08 mail dovecot: submission(user at host.com)<14972><ko4tJitpt9JYSSSC>: Debug: smtp-server: conn 22.73.xx.144:53943 [0]: Sending replies Apr 6 12:02:08 mail dovecot: submission(user at host.com)<14972><ko4tJitpt9JYSSSC>: Debug: smtp-server: conn 22.73.xx.144:53943 [0]: command MAIL; 501 reply: Sent: 501 5.5.4 Invalid FROM: Missing '<' at beginning of path Apr 6 12:02:08 mail dovecot: submission(user at host.com)<14972><ko4tJitpt9JYSSSC>: Debug: smtp-server: conn 22.73.xx.144:53943 [0]: command MAIL: Destroy Apr 6 12:02:08 mail dovecot: submission(user at host.com)<14972><ko4tJitpt9JYSSSC>: Debug: smtp-server: conn 22.73.xx.144:53943 [0]: command MAIL; 501 reply: Destroy Is there a chance that you will incorporate a fix (be more compatible but less stringent)?

I am not a great fan of being liberal by default. That way, violations like that will never surface. We will discuss this internally.. Regards, Stephan.
