Absolutely. I didn't notice that before. > If tao is down should I put ns1.thought.org as a mail > relay/MX site? You should configure ns1 to relay its mail to tao. The idea being, if tao goes down, or is temporarily overwhelmed, ns1 picks up the mail and trys to relay it on to tao. Once you've got tao back up, ns1 will pass all the mail it has on to tao where people can retrieve it. With certain systems, you can also have tao & ns1 both hold the mail and your clients will try connecting to both to retrieve it (or you have a seperate pop server that both tao and ns1 pass the mail to) But these are high-availability solutions, if you need that kind of reliability, you'll have a bit more work to do. -- Bill Moran Potential Technology http://www.potentialtech.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
