Compatibility of Submission in 2.3.1

[Paul Hecker]

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>”):

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

Thanks,
Paul
