      the 90 mails just being dumped into mqueue? Based on the
      message log
      they've been scanned.

Sendmail has throttling features that might stop it receiving and/or
delivering during high load averages. You should shut down MailScanner
and Sendmail and look for zombie processes that stay alive afterwards.
I've had a few problems with DCC and Clam. Kill them if you find any. To
deliver the 90 mails that are already in the outbound queue issue
"sendmail -q" on the prompt. Add -v if you want to see the progress. Have
you thought about that having 90 outbound is not uncommon due to spammers
not receiving mail themselves. Mail therefor floats in the queue for five
days before being deleted, you should be able to see strange domain names
when using mailq if that's the case.
