Mail Server recommendations

[Jim Durham]

Hi,

We currently have a dual-1.8 Xeon box with 2gb ram and Raid-1 
160mhz SCSI's running sendmail/procmail/spamassassin and clamav.

Our place is growing, adding users and so, we need a bigger, 
faster box.

Question:  Currently the box mentioned is a Dell PowerEdge 2650.  
We like to deal with Dell, but it's not absolutely "written in 
stone" that I do so.  I bought a 2650 because we got one to run 
a Windows server and I booted FreeBSD on it to see what it would 
make of the PERC3 Raid and all that and it was just fine. The 
2650 just 'loves' FreeBSD, so we bought one and its worked well, 
but we need more performance now. What bigger, faster box would 
make a significant jump in speed and capacity runs FreeBSD well?

I can get a 2850 with 3gb processors, 320mhz SCSIs and add more 
RAM, but I'm not sure that would give us a quantum-leap in 
performance.

-- Thanks for any suggestions..
