I think this is the major bottleneck - Disk writes,
thus the reason for RAID 10 (I can't reduce the amount of logging for
MS)

MailScanner config:
Log Spam = yes
Log Permitted Filenames = no
Log Permitted Filetypes = no
Always Looked Up Last = no
Detailed Spam Report = yes
Include Scores In SpamAssassin Report = yes


>also you don't mention what version of everything you >are running..
mailscanner-4.24-5
SA 2.63
Jan version of Sophos (no SAVI, good idea though might try)
clamscan / ClamAV version 0.65

RBL in MS - Spamcop, Spamhaus, CBL (with NSCD)
