Only if www.your.domain had its own MX record. Usually, if the website (what else would www. be?) would be associated with the domain of your.domain, and so it would go to [EMAIL PROTECTED]; your.domain would have na MX record of a.mx.your.domain which would point to the system that handles the mail, which could be completely serate fromthe system that handles www.your.domain example: www.your.domain A => 176.16.2.13 your.domain A => *does not exist* your.domain MX => 10.23.45.67 http requests for www.your.domain would be answered by the system at 176.16.2.13, but mail sent to [EMAIL PROTECTED] would be delivered to the host at 10.23.45.67. Mail sent to [EMAIL PROTECTED] would (lacking an MX record) be delivered to the host at 176.16.2.13 -john -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
