[IMail Forum] Really poor performance backing up the queue

I've been trying to track down some really poor performance on our mail server the last couple days as its slow delivery is becoming a problem. A couple days ago we took over another hosting another domain's email, but I can't seem to make a definate coorelation here. Some mail stats to give an idea of the volume this server handles:

Day before transfer:

Domain                      # In  # Out    Bytes In  Bytes Out
--------------------------------------------------------------
domain1.net                36464   1701   310067122  129003006
[postmaster]                   0   7619           0   19343341
domain2.net                 1950    317    30006230   16592255

Day after transfer:

Domain                      # In  # Out    Bytes In  Bytes Out
--------------------------------------------------------------
domain1.net                27123   1063   286810204   49532189
newdomain.net              17966    422   184149770   29170244
[postmaster]                   0   5986           0   15372554
domain2.net                 1611    208    29166077    9173684

Just a bit ago:
D:\IMail\tools>spoolviewer

# E-mails being received right now:         805
# E-mails being delivered right now:        51 [91 recips]
# E-mails awaiting re-tries:                3956 [4358 recips]
# E-mails awaiting first delivery attempt:  0 [0 recips]
# Overflow E-mails:                         0 [0 recips]
# Orphaned E-mails:                         970

We do run Declude 1.75 Pro (both Virus & Junkmail), but on a per user basis (about 400 total users configured for it). Looking in Task Manager, Declude does seem to be taking up a good amount of cpu usage (spikes to 100%, drops, then spikes again). It is also common to see about 20 instances of declude running.

Specs:
Window 2000 Server, SP 4 all updates
Imail 8.10 HF2
Declude 1.75
CPU: P4 2.4 GHz
Mem: 1GB

Any ideas or suggestions are welcome. If any more info would be helpful, let me know. ::James Nelson
