    No, I am addressing two different points.

1: It was said that, according to RFCs, it is the server that generates MSGID.
I refuted that by pointing out that according to RFC822 the MUA legally can.

2: I then stressed that nearly all other similar products across three
different networks, all of which employ MSGIDs, have historically had the user
agent, not the transport agent, assign a MSGID and that PMMail was not falling
in line with this established behavior as it should.

    IE, let's take a different case.  If PMMail didn't quote with the > string
and didn't provide any means to force it to do so people would consider that a
bug even though the > quoting is not an official standard.  It is simply what
has become common practice and convention over the past decade or two.

    Just as some SMTP servers take care of the DATE header if the MUA doesn't
even though this /is/ a required header (one of the 3 minimum headers for a
basic message.  DATE, FROM and TO/BCC).

    So... what does the copy in your sent-mail folder contain?
