4.2 is the wrong section (unless different rfc2822 are sectioned
differently).
The problem is that my two extra lines are not part of the header :)
Please quote the specific section that allows putting "a line with nothing
preceding the CRLF" between the real headers and more headers.
I'll admit that I don't know the mail specs perfectly. But I do have
experience with email message parsing: I have done POP3 server development
for around six years and have maintained vm-pop3d for over four years;
taught mail server administration for over four years; and I have read a
lot of exim, postfix and sendmail MTA code and mail.local MDA code (and
other SMTP mailers) and wrote and use "mailout" SMTP-out sendmail
replacement.

We should track down specifically what mail *tool* lost my important :)
email message. I agree with Kurt: it's a bug that needs to be reported.
Please see

and

Does anyone know where the lines were lost?
I am interested in solving this. Other readers: please let me know if my
two lines were missing for you.
