[Dovecot] Running just part of dovecot

[Marshal Newrock]

I'm currently setting up a large mail system, with different services
split out onto different machines.  What I want is this:

machine1: dovecot smtp auth, no pop/imap
machine2: dovecot lda, no pop/imap
machine3: pop/imap, nothing else

machine3 is obviously not the issue.  Is there a way to run machine1
and machine2 with just their respective services, but no pop/imap?
