CPANEL MX, CNAME and A records

[teddymills]

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.

if your daomainname mydomain.com.

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

[dgbaker]

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

You had those memorized, didn't you?

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