next in thread | raw e-mail | index | archive | help
I recently added a CNAME for a domain, but in doing so, I lose my MX
host for said domain, an example:
[named.conf]
zone "whatever.com" {
type master;
file "/database/named/records/whatever.com";
}
[/database/named/records/whatever.com] *before changes
@ IN SOA ns.govital.net. hostmaster.govital.net. (
2000070501
10800
3600
8432000
38400 )
IN NS ns.govital.net.
IN NS ns2.govital.net.
IN MX 100 mail.govital.net.
mail IN CNAME mail.govital.net.
www IN CNAME web001.govital.net.
ftp IN CNAME web001.govital.net.
When I use this file as the zonefile, it all works fine, sendmail
returns 'mail.govital.net' as the domain's MX host. After I change it by
adding the following, I get no MX host returned by sendmail, but I can
at least now bring up saig website as either 'whatever.com', or
'www.whatever.com'. I understand that it would be preferable to use A
records to CNAMEs so as to eliminate a second lookup; however we are
looking at changing our upstream provider (and thus our IP blocks)
shortly and would rather just have to change the records for
govital.net, than every site we host.
[/database/named/records/whatever.com] *after changes
@ IN SOA ns.govital.net. hostmaster.govital.net. (
2000070501
10800
3600
8432000
38400 )
IN NS ns.govital.net.
IN NS ns2.govital.net.
IN MX 100 mail.govital.net.
IN CNAME web001.govital.net.
mail IN CNAME mail.govital.net.
www IN CNAME web001.govital.net.
ftp IN CNAME web001.govital.net.
I even tried changing the file to include absolute mappings rather than
included tabs, like this:
[/database/named/records/whatever.com] *after changes
whatever.com. IN SOA ns.govital.net. hostmaster.govital.net. (
2000070501
10800
3600
8432000
38400 )
whatever.com. IN NS ns.govital.net.
whatever.com. IN NS ns2.govital.net.
whatever.com. IN MX 100 mail.govital.net.
whatever.com. IN CNAME web001.govital.net.
mail.whatever.com. IN CNAME mail.govital.net.
www.whatever.com. IN CNAME web001.govital.net.
ftp.whatever.com. IN CNAME web001.govital.net.
That still doesn't give me my MX host. Any ideas of what I'm doing wrong
here, or of a better way with which I should be doing what I am?
