Trying to create a "portable" reproductable case, I have disabled
encryption, authentication, etc., checking the data sent using an
sniffer, and I see this:

(final datagram):

"""

0x01f0: 2d2d 0d0a --..

"""

The datagram ends with the MIME close tag, a CR+LF and... nothing else.
There is no final "."+CR+LF.

If I add an extra byte in the body of the original message, I get:

"""

0x01f0: 322d 2d0d 0a2e 0d0a
"""

Here we have the final "."+CR+LF!!!!!!!!!!!!!.

Something is wrong with Thunderbird, seems.

Wietse, if you can confirm that postfix DOESN'T send to milter modules
the headers, EOH, body and EOB *UNTIL* it has received the complete
message via SMTP, I think I can move this issue to Thunderbird bugzilla.

Sorry for wasting your time.

AFTER Postfix receives the ``<CR><LF>.<CR><LF>'', THEN Postfix
sends headers, EOH, body and EOB to the Milters.
