When will Thunderbird be able again to send PGP/MIME emails? It is able to receive and show them, but not to send them. Especially if attachments are involved many receipients are not able to handle the current format.

With former enigmail the format could be choosen.

And please, don't change the current behaviar in K9mail with OpenKeyChain, because that is my current way to reach others that only support PGP/MIME.
