As we can't be sure and do not know for which attachments
this really happens we do not use async crypt for any
mails with attachments. :-/
Better be save (not crash) instead of nice (async).
TODO: Figure this out.
The log goes like this. We pass the send event. That triggers
a write, which we pass. And then that fails. So it looks like
moving to Outbox fails. Because we can save as much as we
like before that.
Using the IMessage::SubmitMessage MAPI interface works, but
as it is unstable in our current implementation we do not
want to use it.
