I just started to block 69.6.0.0 /16  at the edge router for port 25.
This entire block is in spamhaus and we gets spam from them by the tens of thousands and are blocking at the edge by tens of thousands
this has reduced the load on the modus server

You might want to consider setting that /24 to reject all incoming mail

* This is the modus mailing list *

just a heads-up about this IP...our modusmail server's cpu
was pegged at 100%...finally noticed in the security tab
monitoring that spamhaus had rejected over 6000 requests
from this IP...i added the whole class c to our reject
list and after modus caught up from doing virus scans
the cpu is back to normal.
