After reading the code I see that it should insert Date and MessageId if
client is connected to 587 port[1], in my case it uses 587 port and doesn't
inserted Message-Id nor Date header.

The listers looks like:

  listen on egress port smtps \
         smtps pki mx.catap.net auth <credentials> mask-src filter dkimsign
  listen on egress port submission \
         tls-require pki mx.catap.net auth <credentials> mask-src filter 

and that it uses 587 was just confirmed by tcpdump.


wbr, Kirill
