This is your mail as shown by Gnus after toggling the headers:

"From " lines are for example used in the mbox format[0], so I wasn't
too surprised to find it in my IMAP mails as well. However, you very
well might be right that this is a bug in the MDA (which stores the
mails, including the disputed first line, in a Maildir folder, which is
then served by via IMAP).

I'm aware of that; but I never said that the "From " line is supposed to
be a header field -- it preceeds the email headers.
