	Greylisting caused me to drop my quid pro quo MX setup and
actually pay to run a backup system. There are a number of people out
there selling usermode linux hosting these days in the < $20/mo range. It
seems to be a near ideal solution to my NS/MX needs. A good greylisting
implimentation[1] will support syncing your hosts. ~2.5mo into the
experiement with a 99.8% decrease in spam accepted by the MTA, no reported
missed mail.
