The problem with this approach is that I can't find an option that
prevents exim from timing out during a -bS SMTP dialogue. :-(

Sadly, AOL seem to be dropping a lot of our mail because they assume a
sudden rush from a single source is spam. This is kind of annoying when
you limit yourself to the use of a confirmed opt-in subscriber base. :-)

Part of the solution is to do all routing for aol.com first, and then
limit all deliveries to a single SMTP connection.

The other part is to limit the number of messages delivered through a
single SMTP connection, using batch_max (kudos again for the quality of
the documentation!).
