Currently, we are looking to install a server that will be doing content
filtering for our main e-mail server. I thought I would toss this out to
everyone to get some feedback on if the server would be adequate.
The server is a Dell PowerEdge 6850 with the following:
- Four 2.6 GHz/800Mhz/4mb Cache Dual-Core Intel Zeon 7110M processors
- Eight GB DDR2 400Mhz ram
- Four 300GB, 3Gbps, SAS, 10K RPM Hard Drives running Raid-5 on a
PERC5/i controller
Our main e-mail server services over 500 domains with an account total
of around 40,000.
The current filter server we have can not do any content filtering
outside of itself (i.e. the MTA) because of CPU load (i.e.
SpamAssassin). Any message scanning where the message size is over 1.5K
will kill the CPU. The current filter server we have in place is
rejecting an average 2.4 million per day with just the common
blacklisting and some other things that are set in place.
The other thing I would like to know is what kind of an operating system
would one install on this new server?
Again, I appreciate any feedback that can be said.
