Yes, I think the whole CNAME is useless here anyway.

CNAME is useful, but it does not (and can not) work the way you want.

These were the recommendations of this service provider, mailgun though..

where? the CNAME issue is long known and clarifies in RFC 2181, section
10.1. CNAME resource records
...published in 1997.

Aihe: Re: CNAME / TXT

If you uncomment that mg CNAME you end up with a CNAME mx and TXT at the same node in to 
the DNS tree and that is illegal. That is why you get the error "cname and other 
data". The mx and txt are the other data.

Only when I comment out the two lines in the end of the named.harriot, it goes 
through and BIND load the zone. With those two lines, get the following:

C:\DNS\etc\namedb>named-checkzone harriot.fi<http://harriot.fi> named.harriot
dns_master_load: named.harriot:33: mg.harriot.fi<http://mg.harriot.fi>: CNAME 
and other data
dns_rdata_fromtext: named.harriot:35: syntax error
zone harriot.fi/IN<http://harriot.fi/IN>: loading from master file 
named.harriot failed: CNAME and other data
zone harriot.fi/IN<http://harriot.fi/IN>: not loaded due to errors.
