Thanks for this fix - works for me!

Nonetheless there is still another issue with such kind of messages: In the message list, attachments are not indicated (the 'paper clip' icon is missing).

I guess you have to live with this tiny glitch. The attachment icon is "detected" by analyizing the Content-Type header of the message. In the case you're probably referring to, the content-type is multipart/alternative with a nested multipart/mixed which would indicate the existence of attachments. Thus the detection misses this one.

But for message listing we only fetch the headers of the messages from IMAP and analyzing the entire structure of each message would be too expensive in message listing just for the sake of displaying an icon.
