Hi, thanks for assistance!

Yes I can see the headers and yes they are "Content-Type:
multipart/alternative"

I found your earlier mail and for now I have tried saving one of these
mails (that creates a something.mbox file) and to my surprise the
"kmailviewer" informs me it is multipart but only one part will be
shown... and then views it perfectly!

I simply edited away the html part (there is plain text and then an html
part), saved it and imported it and that works. Though that is VERY
tedious work given the amount of email I am dealing with here.

Wish there was (at least) a way to do it from inside KMail or some
setting "with multipart only show one part" if you get what I mean

kind regards,
Sinclair
