Yep.
Make sure Exim runs in "queue only" mode as a daemon, which will result
in ezmlm punting the messages into Exim's queue (while Exim then does
not try to deliver them straight away). Alternatively flag the domains
in question as "queue_smtp_domains".
Then run a queue runner periodically (how frequently is up to you) and
Exim will automatically attempt to deliver as many messages as possible
down the one connection. If you want to be clever about it, run the
queue runner as "exim -qq" which will definitely attempt to deliver as
many messages as possible down the one connection.
