[Mailman-Users] Missing headers of postings

[Roland Studer]

Hi there

Suddenly postings on our Mailman (2.1.5) list are missing headers, the
mails sometimes arrive without any Information about the sender or the
subject. The headers From and Reply-to and Subject are missing.

In addition I wanted to send a HTML-Email with an attachment: It
wasn't displayed correctly, the display of the mail began with the
following.

--===============0751753693==
Content-Type: multipart/alternative; boundary=Apple-Mail-1-691538562

What could cause this, what can I do about it?


Below is the beginning of the original Mail including headers.

Thanks a lot for your help!
   Roland
