Hello

2 weeks ago I wrote about org-mime-htmlize, which html
emails and converts latex formula to embedded png.
I attach the corresponding htmlized message below.

The resulting mail is displayed in a couple of email
The reason is that the message contains the line
 Content-type: multipart/mixed; boundary="=-=-="
in its header while thunderbird requires 
 Content-type: multipart/related; boundary="=-=-="
and the thunderbird developers insist that this is the 
RFC 2387 standard.

Could gnus offer this possibility or maybe it is already
there and I miss the relevant setting?
Thanks
