Bingo.
This machine was using my authoritative slave and for some reason it did
not update the zone yet.
I changed the resolver then:
opendkim-testkey: checking key 'dkim1._domainkey.iwtelecom.com.br'
opendkim-testkey: key OK
But I found something else: when I send a message the destination server
is not checking my sender's domain key, it is checking my server's
hostname instead, wich is app1.iw.net.br.
So I had to create to more records: dkim1._domainkey.iw.net.br and
dkim1._domainkey.app1.iw.net.br
Now Gmail says DKIM is ok:
DKIM: 'PASS' com o domínio app1.iw.net.br

I figured it out at least on my host as to why one would get 'record
not found'.
My mail host has entry in resolv.conf 'nameserver 127.0.0.1'
I have named config file for my domain to resolve to this mail host,
192.168.x.x
running
# opendkim-testkey -vvv -d whitehorsetc.com -k
/var/qmail/control/dkim/whitehorsetc.com.key -s dkim1
yields 'record not found'
when I change resolv.conf to external nameserver (8.8.8.8)
# opendkim-testkey -vvv -d whitehorsetc.com -k
/var/qmail/control/dkim/whitehorsetc.com.key -s dkim1
yields 'key OK'
You must add a TXT record to whichever DNS server your mail host is using.

Maybe restart your named server.

Looks like I was checking it the wrong way, the correct is:
# dig dkim1._domainkey.iwtelecom.com.br TXT
;; ANSWER SECTION:
dkim1._domainkey.iwtelecom.com.br. 86400 IN TXT "v=DKIM1\; k=rsa\;
p=blabla...blabla"
Checking the key at https://dkimcore.org/tools/ looks fine also.
The opendkim-testkey still shows the error though.

Hi everyone,
I'm doing the DKIM step for a new server and when I test my DKIM
signature I receive the error:
# opendkim-testkey -vvvv -d iwtelecom.com.br -k
/var/qmail/control/dkim/global.key -s dkim1
opendkim-testkey: using default configfile /etc/opendkim.conf
opendkim-testkey: /var/qmail/control/dkim/global.key: WARNING:
unsafe permissions
opendkim-testkey: key loaded from /var/qmail/control/dkim/global.key
opendkim-testkey: checking key 'dkim1._domainkey.iwtelecom.com.br'
*opendkim-testkey: 'dkim1._domainkey.iwtelecom.com.br' record not
found*
I created the record in the domain zone like bellow:
dkim1._domainkey IN TXT "v=DKIM1; k=rsa; p=bla...bla"
But it does not work when I try to resolve it:
dig dkim1._domainkey.iwtelecom.com.br
And it is not shown when I try:
dig +noall +answer iwtelecom.com.br any
Only the SPF record... I used the named-checkzone and everything
looks fine, what am I doind wrong?
