This is still corrupted according to git am unfortunately.  I can't
immediately spot the issue.

The v3 I sent applies just fine with "git am" as far as I can tell. I just tested it again with the mail form the list.
I think the v3 patch is fine, but this time, the v3 message ended up with the same message ID as the v2 message.
Because of this, some mail clients may get confused, and the threading in mail clients is going to be broken.

I think this time it should work. It's surprisingly difficult to get roundcube to not alter plain text messages. Sorry about that.
