A few questions I can't find in archive...

[MailScanner]

All the trimmings: tmpfs, caching DNS, local lookups.

We do have a large (20k) number of messages in the outbound queue.

72K is not that many for a dual xeon, sounds strange. Are you using
tmpfs also ? Do you have a RBL lookups on a local server or all on the
