mail IN CNAME some.mail.server
So you can have a CNAME pointing to MX, but not MX pointing to CNAME.
Also, I don't understand the relation to the Google example. The support page you
mention gives a
list of MX records with names that are all A and AAAA records, no CNAME involved at all.
In practice, it appears that the CNAME works with some mail transfer agents. But bind9 is
complaining.
The literal IP address in an MX record results in 2 warnings, one that there is an address
in the MX record
and another that the 111.222.333.444.ampr.org is not defined. This of course is because
an address is not
expected there, and it is treated as a domain name relative to the $origin of the zone.
When your server has no associated name, of course you can assign one within ampr.org.
Also, when you want your server to SEND mail in addition to RECEIVING it, you need to have
a name and a
matching reverse, or many spamfilters will just drop your mail on the floor.

I can tell you that GMail's MX RR's work in this fashion. I
don't need to
know their A record for my DNS. I just add their CNAME'ed MX records to my
domain files and my mail shows up. And my domain isn't hosted by them.
Just my mail hosting.

Using a CNAME in your domain breaks your email because sendmail (and
possibly other SMTP software) will rewrite the domain portion of the
destination email address to that of the label in the CNAME. See also
CNAME records in mail by D. J. Bernstein[1]. Note that having a CNAME
for example.tld is of course impossible unless you get the tld to have
the same record. Having an MX point to a CNAME record causes additional
DNS lookups, which might cross a threshold, and thus cause your mail to
be dropped. Additionally "Mail loops back to me" errors might be caused
by this. Also see RFC1034[2] - DOMAIN NAMES - CONCEPTS AND FACILITIES
for more details. In short: Don't use CNAMEs in relation to SMTP.

It all originates in requirement that all 44net DNS record must be in
the same DNS.
It would be better to let people simply set NS records for their domain
and handle DNS on their own name servers. That is how DNS is designed
and it is natural and logical way to do.
If someone sets it wrong it is his problem.

The problem is that it's only one domain, ampr.org.
So unless it is splitted so that each uses subdomains it makes no sense to

Here is a non-subdomained address:
*aa6hf.ampr.org*
Name: aa6hf.ampr.org
Address: 44.17.0.128
aa6hf.ampr.org mail exchanger = 10 aa6hf.ampr.org.
aa6hf.ampr.org mail exchanger = 20 linux.aa6hf.ampr.org.
Authoritative answers can be found from:
*ampr.org nameserver = hamradio.ucsd.edu.*
ampr.org nameserver = munnari.OZ.AU.
ampr.org nameserver = ns1.defaultroute.net.
ampr.org nameserver = ns0.comgw.net.
ampr.org nameserver = ns2.threshinc.com.
ampr.org nameserver = ampr.org.
ampr.org nameserver = ampr-dns.in-berlin.de.
ampr.org internet address = 44.0.0.1
It is not a subdomain, it's address is
served by the ampr.org nameservers.
Here is a delegated subdomain (some lines removed for more clarity and
less clutter):
*de.ampr.org*
de.ampr.org text = "de.ampr.org - Seit 2012-03-17 im Testbetrieb.
hamradio.ucsd.edu *delegated*"
de.ampr.org mail exchanger = 20 kle.nw.schule.de.
de.ampr.org
origin = de.ampr.org
mail addr = ipkoord.de.ampr.org
Name: de.ampr.org
Address: 134.91.19.148
*de.ampr.org nameserver = db0res.ampr.org.*
de.ampr.org nameserver = db0fhn.efi.fh-nuernberg.de.
de.ampr.org nameserver = ns.db0fhn.ampr.org.
de.ampr.org nameserver = db0res.de.
It is a subdomain because it is being served
by de.ampr.org name
servers, not ampr.org. No x.de.ampr.org addresses are served by
ampr.org. This can be further subdomained, as many times as needed.
Subdomaining hands off (delegates) the responsibility for a namespace
(e.g., de.amp.org) or a range of IP addresses (e.g., 44.130/16, meaning
44.130.0.0 through 44.130.255.255) to another entity and nameserver(s).
The advantage of a delegated subdomain is that you can update your
subdomain's DNS records without having to get someone else to do it.
The disadvantage is that someone must install, maintain, and operate a
DNS server. I do this for my own (non-ham) domains, but I've had decades
of experience with DNS servers (I have been working with the Internet
since before DNS was created, ALL of the hosts that were public were
listed in a single file and installed on every host! :-), not everyone
wants to go to that effort.
I'm just getting back into Packet Radio and the 44 net after a decade
and a half dedicated to work and family, and I'm still learning how
things have been put together in the intervening years.

As I thought it is just matter of term definition. I use subdomain as
broad definiton of domain which is under some other domain.
By that definition this is subdomain. It is just hosted in the same DNS
as top level domain.

I agree this is also subdomain.
The advantage of a delegated subdomain is that you can
update your
subdomain's DNS records without having to get someone else to do it.
The disadvantage is that someone must install, maintain, and operate a
DNS server.
Atually, there are few quite nice online DNS service that provide DNS
hosting for free.
http://afraid.org offers very simple user interface that allows anyone
with any knowledge of what domain is to set what he needs.
http://xname.org/ is full powered DNS server, also free. It does require
some advanced knowledge to set it up.
Thing is, when I asked to set ampr.org subdomain on my own DNS server,
it was refused. It was said that it is not allowed, and all subdomains
must be set on ampr portal.
My point is that prohibition should be removed. If one wants to set his
own DNS for subdomain he should be let to.

It is normal for you to be refused.
Allowing you to provide name services for ampr.org would mean you need to
provide ALL name services for *.ampr.org, which is obviously not the case.
And that restriction is valid and correctly applied and should NOT be
removed (which is actually not possible btw).
The correct name servers are registered at the proper TLD, and seting an
arbitrary other server would mean that anyone could alter the DNS for the
domain, without asking anybody, potentially with malicious intent.
So the only option is to serve a subdomain, which means that e.g
*.yt9tp.ampr.org, for which you need to provide a DNS and be proper
delegated by ampr.org, without the possibility for you to alter the parent
DNS..

We allow complex hostnames in the left hand side of the master AMPR.ORG
DNS servers, so it's quite possible to have names like those above as
the LHS of A or CNAME or MX records. Because you can do this and because
callsigns are unique worldwide, we usually don't need subdomains and
delegated name service.
One reason we don't allow arbitrary NS records is the issue of reverse
lookups - the corresponding PTR records. When you register a name such
as 'yt9tp' as an 'A' record in the AMPR.ORG domain, we automatically
generate the corresponding PTR record in the 44.in-addr reverse domain.
If we delegated e.g., yt9tp to another nameserver, we would not be able
to generate the proper PTR record, and neither would they. I don't like
the idea of there not being a corresponding PTR record for each A record;
I believe that is poor networking practice and strongly discourage it.
It would require delegating arbitrary parts of the 44.in-addr domain,
which is a whole bag of worms I don't like to do without a really good
reason. Depending on delegation width, it can be a painful process
requiring significant manual intervention in the DNS database so I do
it only for exceptional cases involving directly-routed subnets.
There are seven AMPR.ORG and 44.in-addr DNS servers located around the
world. The chance that all of them will be down at once is close to zero.
We allow people to AXFR their content so it is perfectly possible
to have a redundant DNS server on your local net which can answer queries
regarding those zones even if you are partitioned from the Internet somehow.
(Although if you really need your DNS resolution to work in the face of
disconnection from the rest of the Internet, you'll possibly need to supply
your own cache of the root and .ORG servers as well - depends on how your
DNS server does its lookups.)

You can run a robot script and import the two zonefiles into a local DNS
server if you wish. These are updated periodically every so-many-hours
and are available via FTP from ucsd. One needs not be a registered slave
DNS. Just import the two zonefiles into your local nameserver and reload
it.
Years ago I was one of the secondary slave servers but now with the
excessive volume of DNS exploiter robots hammering away at the internet,
I'm almost glad I don't anymore.

Hi Gang
May I suggest our solution to the same issue
Was to register our own domain ampr.org.au (Australia). I have had it for
many years from when packet was at an all-time high, and due to differences
to get things done and ip space was hard to get done.
So a few people back in the day got me into packet on a subnet and until I
got access to the AMPR ORG dns my solution was to do what I did.
I can see what he wants to do here and use his own dns -
Maybe consider getting your own domain name that sits within your countries
dns naming structure and use it as well as the ampr.org portal
I can see why people don't want to allow sub domains in the ampr zone file.
Starters it is populated with stations that no longer exist.
I still use the ampr.org.au zone file today as there is entries that can't
be entered into the ampr.org zone
Finally in regards to ampr.org zone
It may not work to everyone's need, but it works the majority!

If you're looking to be able to serve ampr.org dns resolutions for your
local region you may want to do that.
However, for wanting to host just your portion of it and remap it to another
nameserver just go as far as the whois servers. ampr.org is listed but
yt9tp.ampr.org is not:

Was to register our own domain ampr.org.au (Australia).
Sure. I gave up using subdomain of ampr.org and decided to use my own
domain.
I just thought that idea is that we all use subdomans of ampr.org.

In the DNS hierarhy you have Top Level Domanis (TLD) in the root zone (like
.com, .net and in our case .org).
Then you have 'ampr' as single domain.
All entries resolvable directly to an host IP in 'ampr' are in this domain
and are not delegated.
e.g. yo2loj.ampr.org (44.182.20.36).
If I would set up a subdomain, I would have different machines with
different IPS under yo2loj.ampr.org, an that would be a subdomain.
e.g. mail.yo2loj.ampr.org, www.yo2loj.ampr.org, ftp.yo2loj.ampr.org,
ns.yo2loj.ampr.org and so on.
In that case, name resolutions could be delegated for all *.yo2loj.ampr.org
names to lets say ns.yo2loj.ampr.org and I would need to maintain my own DNS
server(s).
That means that in a DNS resolution there would be 2 lookups, first one to
the ampr.org NS to get my NS as defined there, and a second lookup to my
local NS to resolve that name.
And it also means that if my NS is down, resolution will not be possible.
Now if one uses a single <callsign>.ampr.org with one IP, this is resolved
directly at ampr.org level, avoiding both issues, but keeping the name
resolution out of his hands.

Can you point out of some sample of domain usage which is not subdomain?

New subject: Bad MX records in the ampr.org DNS
While we're on the topic of DNS, I've noticed some of the newer MX
records aren't properly functioning for some reason. gmx/gmail/yahoo and
some of the other more local ISPs ie: Optonline, Comcast, Cox mail
systems can't resolve some of the newer entries.
I have seen cases where a point within a domain has their own MX
records, and others also exist but one contains an error, the rest of
the MX records may get ignored. As it stands now, n1rcw.ampr.org is
resolvable as a point within ampr.org but it's MX record (which does
properly exist) is showing unresovable by some of the above mentioned
mail servers.
It's always good to keep DNS records as error free as possible as funky
things can (and most likely will) happen because of such.
