I'm running a PTR record because I want my host name, domain name to
resolve (and I agreed with my ISP I was running 'primary'.)

By "primary upstream PTR" I meant - when I did a local country domain
registration... I received a "No PTR records found" error:
>>>>>>>>>>>>>
CHECKING: Primary Server is myhost.mydomain.com at xxx.xx.xxx.xx
WARN: No PTR records?  - INFO: At xxx.xx.xxx.xx

CHECKING: secondary 1 is ns2.myisp.com at xxx.xx.xxx.xx
INFO: Name "isphost.ispdomain.com" - INFO: At xxx.xx.xxx.xx
>>>>>>>>>>>>>>.

Whereas - the hostname, domain name is resolving (on the nameserver lookup)
- and I am definitely running a PTR record (as previously recommended by
you, i.e., one PTR record per IP)... ergo... if I am running a PTR record
and the name is resolving... but the bot is telling me there are no PTR
records then the error must be somewhere else... my ISP's primary?

By upstream I meant: I'm at the end of a request chain(?) - therefore
everything else must be upstream(?) This is now fixed - with no change on
my end... though I did mention to my ISP I was seeing the error.

Okay - finally got this straight :)

In my understanding a "Primary nameserver" resolves hostnames to ip numbers
and vice-versa. If a PTR record is part of this function - and I'm not
running a ptr record... then I can no longer be a nameserver, i.e., if I am
not resolving hostnames then I'm not running dns? I set this up with my ISP
on the understanding I was doing primary and they were doing secondary.

Don't understand the 'delegation' part - thought reverse mapping was part
of my function of running primary dns?

Sorry - I registered a nameserver - it has a fully-qualified domain name -
it is registered as the primary nameserver for my domain... Gee whiz... I
didn't make it complicated... I just discovered it is more complicated than
it seems :P

Thought the PTR record _resolved_ the hostname and domain name.

This may still be true.

> If you want

My sites are resolving - and everything looks beautiful - including the new
domain - which will have no errors thanks to the help on this list.

Now - if I can just sort my email problem... well, the emails working...
but - it gets complicated :P Maybe next time.

Thank you all for your help.
Cheers - Patrick.
PS. Jeff - please don't feel you have to reply to this - though your input
would obviously be appreciated.
