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!
