Thanks Sandy, dully noted.

I do host accounts, but I'm not pushing that side of my business.  Currently it accounts for only about 1/5 of my E-mail volume, the rest is gatewayed and growing.  I'm not sure though if I want to move it to the new box or not though.  I need to do envelope rejection for invalid addresses on gatewayed domains (old discussion), and the work around is using ORF+MS SMTP which can't coexist on the same port as IMail, and I need IMail on port 25 for SMTP AUTH.  The work around may be to configure MS SMTP on port 25 and a unique IP, and IMail on say port 2525 on a unique IP, and have the router do port forwarding on IMail's IP from 25 to 2525.  That way both could co-exist on the same box.  If I can get that to work, I'll move everything over.  Web mail however is rarely used and won't present any challenges.  I guess I could use a Syslog server to take that burden off of the server, and it would be easy to test by turning the logs off and on as far as what that would do.  Declude of course won't syslog for the time being, but I'm buying myself a lot of time I figure.

Placing Declude and Sniffer on it's own drive (if RAID 10) is something that I was overlooking and probably should be considered.  So maybe 3 logical drives would seem immediately appropriate and maybe more if conditions warrant.

If  you're  using  Web  Messaging  or  Calendaring,  virtual memory is
_always_  used, regardless of the amount of physical RAM, and in those
situations  your  system  will  benefit  from  multiple  swapfiles  on
dedicated spindles. Without WM/WC, your assessment is correct.

In  addition,  if  providing  WM/WC, performance will skyrocket if you
mount  \spool\web on dedicated spindles. From your message, however, I
sense that you are not providing mailbox services of any kind.

  
how about the log's?
    

Well,  think about it: every incoming connection is logged. If the log
is  on  the  same drive as the spool: immediate contention. Dedicating
spindles  to  logging,  or  moving  it  off  the  box completely, is a
near-mandate for a scaleable architecture.
