???? Assuming your mail server is at 10.0.0.1
in domain1.com's zone file: mail IN A 10.0.0.1 in domain2.com's zone file: mail IN A 10.0.0.1 If a browser types in "http://mail.domain1.com";, he will go to the web server located at 10.0.0.1, sending the host header information asking for mail.domain1.com virtual host content. If a browser types in "http://mail.domain2.com";, he will go to the web server located at 10.0.0.1, sending the host header information asking for mail.domain2.com virtual host content. IF this is the way you had it setup, but someone typed "http://mail.domain2.com"; and got redirected to http://mail.domain1.com, that would be a function of the web server at 10.0.0.1 sending a redirect, NOT DNS (again, assuming your DNS is setup along the example above). For example, you can go to: http://www.intouchmi.com/ http://www.flintgenerals.com/ http://www.lakeagency.com/ All three of these sites point to the same IP using A records. The only difference is how the web server is configured to see those host headers. There are no CNAMES in use at all here. I hope this example helps out. - Tony >I can't do that because we have to display slightly different >content to different users and the only way we can distinguish the >user is by what address they typed in.
