There isn't any technical reason why MUA software can't do its own
delivery with today's technology.  The whole concept of "outbound MTA"
seems like a throwback. With the exception of delivery delays, but
having a MUA attempt its own delivery and then switch to the smarthost
on connection or other temporary failure wouldn't require any
inspiration.

As if web-service MUAs are going to fade away, which is doubtful.
