Blank lines inserted into header...

Here's a bit more information.  I am still having the problem - I have
noticed it's with any X- header that may be "too long" whatever that
may mean.

For example, I got an email that had the following header in it:

-9194dd1a3dbc}: F:\Program Files\exclaimer\eXclaimer.dll -

and it has a blank line preceding this in the output of
mailscanner/sendmail.  This effectively makes this header line become
the start of the message body.

However, when I change it to:

    X-Exclaimer: F:\Program Files\exclaimer\eXclaimer.dll -

there is no blank line added and the message headers remain intact.

Therefore, it's not the X-%org-name% logic that I previously thought it
was, but rather it seems to be the length of the header name.  Of
course, it could be sendmail that is doing this perhaps.  I bet I have
a misconfiguration somehow - I can't believe that nobody else is seeing
this same problem otherwise.

Just so everyone knows - here's how I tested:

    cat /file.txt | sendmail butler at    (where /file.txt
has the original email with the blank line removed)

by editing the /file.txt and shortening the X- header name, it works as
it should.
