Eww - should be seeing 5-30 seconds per batch at that level..
Check you're not running ALL the RBL's...you can also put some timing
info into the logs so you can start to find out where delays are..
Log Speed = yes
As Brent said, are you running extra rules in /etc/mail/spamassassin and
if so any large ones (the bigevil family should NOT be used for
example).
Looks like you've got a massive backlog in the hold queue too...I
suggest you're doing more than 7,500 messages per day...do you drop
unknown addresses on the inbound (pre) MailScanner postfix??? You can
easily drop 50% of the traffic then and there using that technique.
