Greetings everyone, 

I HAD a Windows NT 4.0 machine running Imail version 6.xx (latest patches, etc) with 
Declude anti-spam and anti-virus with sniffer from sortmonster.  Everything ran fine 
until last friday morning when BOTH mirrored drives crashed.  When I went to the shop 
both drives were "clank, clank, clank...."   

I build a new machine with Windows 2000 advanced server and installed Imail and all 
the latest patches.  I have installed declude and sniffer.  I am using F-prot for the 
virus scan through the declude program.  On the NT 4.0 machine running an AMD 750 
processor the cpu usage on the task manager showed between 2 - 5% with peaks around 
40%. 

On the new 2000 machine running a 1.8 Ghz intel 4 it will also run about the same cpu 
usage.  Then it starts showing usage averaging about 45% with peaks to about 90%.  The 
performance monitor shows the "File control bytes/sec" is showing about 250,000 per 
second.  Normally this is 400 -500 with peaks to 4000-5000.   

This is driving me nuts as I can't seem to find what is causing the problem.  The 
"sys0803.txt" shows ALL the same entry - "08:03 12:55 1884 LST 
imailsrv->[EMAIL PROTECTED] Illegal IMail List Server Command!"  The 
ENTIRE log file contains the above entries showing the only differences to be the date 
and time.  NO OTHER NORMAL ENTRIES are in there! The daily logs are over 25 meg with 
nothing but that entry.

I have turned OFF the logging and the problem still exists.  If I reboot the computer 
the cpu usage goes back to the normal 5% usage.  Then all of a sudden it jumps to 35 - 
50% usage.  There is no pattern to the amount of time before it happens.  Last night 
it took almost an hour before it happened.   

I have approximately 100 domains running on the computer with about 4760 users.  Keep 
in mind that the windows NT 4.0 running the same domains and users did NOT do this.  
It started with the Windows advanced 2000 server.   

The declude anti-spam and anti-virus program is STILL catching about 25,000 pieces of 
spam per day as it did on the NT 4.0 machine.  I even have the declude set to DELETE 
the spam and virus instead of holding it to save disk writes.   

Any assistance with this problem will be greatly appreciated.
