some webmail places have you enter a CNAME record for their site. this
has nothing to do with mail delivery (and you obviously can't do it the
way he's described here).... but what you could do (as i indicated in
another post, but perhaps not clearly enough) would be to do:
@ IN MX 10 mailrecv.bigmailbox.com.
mail IN CNAME bigmailbox.web.site.com.
(everyone.net uses siteurl.everyone.net for example).
this way people can go to:
mail.yourdomain.com
to check their webmail. it's actually one of the few times where i find
using a CNAME record actually quite useful.
this assumes that there is NOT another record for 'mail.youdomain.com',
and that mail is not being received at 'mail.yourdomain.com'.
i think the original poster was just a bit mixed up about the actual
records; the zone file entry mentioned above is _definitely_ not exactly
how big mailbox asks people to set things up.
