Interesting... I forgot about that. Actually, I don't think
you should turn off syslogging completely. On Linux at least,
and probably other UNIXes, you can put something like this in
syslog.conf:
mail.* -/var/log/maillog
The leading dash tells syslogd not to flush to disk after each log
message. That will probably help throughput a lot without sacrificing
logging.
If you're a hyper-performance person, you'll put /var/log on its own disk.
Same with /var/spool/mqueue.
Oh, and did I mention to make sure /var/spool/MIMEDefang is on a
ramdisk? Well, make sure it is!

David.
