If you're doing it via CLI and specify just a single message to be
delivered, it will deliver just that single message. On the upside though,
if there was a delivery problem that caused the rest of the emails for that
domain to be delayed, upon successful delivery of a single message, it will
make exim realize (on next queue runner) that it can deliver to that domain
and it will attempt delivery of pending messages (based on router/transport
settings).

You can set this on your SMTP transport; check out the
connection_max_messages setting in the docs. It defaults to 500, so it
should indeed be doing it "by default". I just noticed also it says you can
use this setting via CLI with the -oB flag.
