The time-to-live. It tells the world how often (in seconds) they should check back to see if this record has changed. You are telling people to check once every 4 hours. > I'm guessing a port of some kind.

Lowest number wins, so to attempt this "trick" you would need to change your current MX to be some number larger than zero so that a fake MX could be inserted lower. But I'm not convinced that twiddling with fake MX records will reduce your spam level any. -- Daniel J McDonald, CCIE #2495, CISSP #78281, CNX Austin Energy http://www.austinenergy.com
