What you can currently do to split your outgoing spool dir up into several
is to use a ruleset to calculate "Outgoing Queue Dir" so that, for example,
internal messages get 1 queue while external (leaving your site) messages
go in another queue. You run a queue-runner Exim process for each of your
outgoing queues. I have seen this done with sendmail to quite good effect.

Gets you speed on internal messages separate from the potentially large
queue of mail leaving your site bound for other (slow) SMTP servers.
