The easiest way is to have domain.com's address be the ip of the domain server, make www.domain.com a CNAME to domain.com, and if you're running sendmail on the web machine, *lie* in DNS and do the reverse to the web server's IP address to www.domain.com, instead of domain.com. This is important because sendmail < 8.9 will answer mail on all of it's IP addresses as reported by DNS whether or not they are in sendmail.cw. 8.9+ has a feature to turn this off. > > 3) If I just take domain.com and make IN A X.X.X.X of the web server, it seems > many stupid mailers out there don't pay alot of attention to the MX record and > report no mailer daemon and bounce. Really? I used to see that alot, but don't too much anymore. However, if you *are* running sendmail on the box, you should allow relaying of the domain on the box, and provided that you've lied in reverse DNS, it'll relay the mail appropriately... --Mark To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
