Yes, your analysis is correct. I normally do the bayes/auto-white
listing in /etc/mail/spamassassin for this reason.. but it does have a
performance hit. If you have a large volume of email, and control what
you can put in your server I would recommend getting a dedicated
SATA/SCSI ramdisk. There are several models around at different price
ranges. They will be slower than a memory ramdisk (you end up at
150MB/s to 300 MB/s depending on the bus you are using..) but you do
not lose data due to built on batteries.
