    Here is part of a cpanel made DNS record for a domain.
    I have read in many places that the MX record must point
    to a domain name. (ie. it is below, mydomain.com.)

    However I thought the line about "www" should be.
    mail IN A 12.12.12.12 (whatever your ip)

    Is "mail IN CNAME mydomain.com." correct or uncorrect?


    ----------------------------------------------

    ; cPanel

    cleansheet.ca. IN MX 0 mydomain.com.

    mail IN CNAME mydomain.com.
    www IN CNAME cmydomain.com.

    Since all your services are probably running on the same machine, it doesn't matter a whole lot whether you're using CNAME or A records for `mail'. You're fine either way.

    If you want some more infor, check this out for some guidelines about when to use CNAME records: http://www.rscott.org/dns/cname.html

    CNAMEs are prohibited in MX records, according to RFC974, RFC1034 3.6.2, RFC1912 2.4, and RFC2181 10.3

    One would hope not. If so I need to find better things to fill the void. :)
