For one thing if you want to use MailWatch, you'll need a dedicated
Postgresql server. Also get the fastest disks you can get (ideally 4
SAS 15K HDD, in RAID10).
The DL380 that we've got is a dual 4-core, 6 GB RAM, and its average
speed for processing a 30-message batch is around 80s, but I think we
never saw it driving 30 messages on all the 15 childs at the same time.
That means that if most of your traffic is between 8 and 17h, you can
theoretically scan 12150 messages/child, during these 9 hours. This is
only the part that reaches MailScanner. BarricadeMX kills the rest. We
get an average of over 500 000 SMTP connexions/day (6/sec) on our
You may want to ask FSL's advice as they've seen many different kind of
setups. They may also help get the best results out of your hardware.
