Wow!  That's incredible.  I assume this is a German Bank?  Only in my
wildest fantasies could I even conceive of such a thing possibly
happening, especially in the US.  I want to use your bank.

Do I've had problems with notmuch if I answer "yes" to the replace
current text question.  It appears to actually modify the file being
decrypted, which in this case is the actual mail message, and that seems
to cause problems for notmuch.  I actually want the text to be replaced,
but just in the buffer, and not in the file.  I haven't looked into this
yet though.

We really need to get some better PGP/MIME support in the emacs UI.
Unfortunately I just haven't had the time to work on it.  I'm at least
glad that other are struggling with it as well, so it's not just me.
