Hi Sunhail,

Your mailing system is sending out emails that contain an invalid
Message-ID header (missing right part of the msgid as specified in [1]),
which causes erratic behavior from other participants (the gmail smtp
servers for example just rewrite the message id to indicate it is
malformed, breaking the reply chain).  Could you please fix this?

This is quite on-topic in a discussion about the mail-based workflow :)
