Why do you need CNAME records? When a mail system wants to send mail,
it looks for an MX record for the mail domain specified in the address.
If it finds one, the MX record should point to an A record.
$ORIGIN example.com.
mail IN A 192.168.42.42
fred IN MX 10 mail
gladys IN MX 10 mail
bert IN MX 10 mail
Then mail to gladys.example.com will result in an SMTP connection to
[192.168.42.42].
If you need someone to be able to ping gladys.example.com, or whatever,
then sure, have CNAME entries.
If you sort that out, does it then work?
