I just used CNAME for the first time ever. Here was my rationale:
I have the new IMail webmail interface at
<http://mail.robintek.com>http://mail.robintek.com
I setup a DNS for a new customer and wanted them to have easy
access to webmail without having to go to my url so I added the
following to their DNS file:
webmail IN CNAME mail.robintek.com.
that's legal, but it does require the 2 DNS queries instead of one.
You can just as easily do this in their domain:
webmail.theirdomain.com A ip.ad.re.ss
... avoiding the CNAME.
And what shows up on the web mail client's browser when aliased to
your domain? your domain, right? Wouldn't it be better if their
domain was in the browser address field?
