Compatibility of Submission in 2.3.1
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@host.com>”):

Is there a chance that you will incorporate a fix (be more compatible but less stringent)?
Thanks, Paul

Any idea which client is doing that?

I can make an option for doing that (some sort of workaround setting). I am not a great fan of being liberal by default. That way, violations like that will never surface. We will discuss this internally..

Stephan.
