I've been wanting to hack this up for ages, to stop my queue getting
clogged with undeliverable bounces resulting from those of my
users who forward to AOL (in particular) which does content-based
refusals after data-phase. It'd also address similar issues
with yahoo et.al. who claim it's far too difficult to validate
a recipient name at RCPT time (blech!).
I had in mind to use the same connection opened for a verify callout,
if possible.
