about to head off home, so just a few things to consider...

have you got the mail queue dir's on a separate disk?

have you checked the RBL's, and made sure non of them are timing out?
What RBL's are you running?

have you got softupdates configured on the file system with the message
queue and MailScanner working directory.

How much memory have you got, and how much swap are you running? (top
will show how much is being used). What CPU is running on the system,
and is the load showing above high when you get these backlogs?

It really sounds like something is slowing the system down, is there
anything in the maillog to indicate this? have you checked the SA files
with --lint?

What happens if you run MailScanner in debug mode, any indications of
slow down/timeouts there..
