That's it! Thank's al lot for this information.:-) At least Dell is sending
out newsletter with 101k bytes in one single line!

Saving the tcp stream in wireshark as ascii, does cause line breaks. That's
why I didn't get an error message passing the dump to exim.
Saving the tcp stream as raw, does show the long lines.

That does make sense. But is it necessary to look at the body, if there isn't
any dkim-signature at all?
