You can use a ruleset for the "Outgoing Queue Dir" setting.

In MailScanner.conf put this:
Outgoing Queue Dir = /etc/MailScanner/rules/outgoing.queue.rules

Then in outgoing.queue.rules put this:

From:   /^$/            /var/spool/mqueue.slow
FromOrTo: default       /var/spool/mqueue

         mkdir /var/spool/mqueue.slow
         nice sendmail -q60m -OQueueDirectory=/var/spool/mqueue.slow

No immediate delivery attempt will be made on messages put into
mqueue.slow. They will just attempt a delivery when the once-per-hour queue
runner sweeps the queue. The "nice" will make that queue runner operate at
a low CPU priority so it can't steal the machine when it sweeps the queue.
