Aihe: Re: [exim] Missing E-mail
Well crap... That's kind of what I've been afraid of was that my issue with
mail "may" be DNS related. What I don't understand is why it's not working
for you when it works for me. The only thing that I have presently set up
on the machine is iptables...maybe I've got something set up wrong there.
I'll turn it off and if you could run the same test I'd appreciate it.

I am fully aware of the implications of having both DNS on the same server.
I'll be working on migrating secondary to another server soon but I really
need to get this one working first before making it even more complex.

Here's what I get when doing just a straight up dig -t mx pleiadesdesign.com

Here's what my "current" zone file looks like after I made some edits and
style changes. Does it look okay? I mean everything that I've checked it
against seems to think it is and that it checks out okay. Bind loads it
fine without error but I'd like to have a bit of re-assurance on that.

Your DNS is rather badly broken. Perhaps your connectivity in general?

----------------------------8< cut here >8------------------------------ %
dig -t ns pleiadesdesign.com

; <<>> DiG 9.4.2 <<>> -t ns pleiadesdesign.com ;; global options: printcmd
;; connection timed out; no servers could be reached % host
lyra.pleiadesdesign.com ;; connection timed out; no servers could be reached
----------------------------8< cut here >8------------------------------

As Eli noted, running all the nameservers off one IP is generally bad.
The reason that multiple NS records are required by registrars is for
resiliency -- it's not pointless bureaucracy.

You can get free DNS secondarying from various sources; I've heard good
things about the http://www.granitecanyon.com/ service. Read the terms of
service (no warranty), try it, consider making a donation if it's useful to
you. They have a decent FAQ, too.

The routers near my box have multiple routes to 69.30.192.0/18, so the
network in general is fine. But if I try to connect to 69.30.204.75 with
TCP on ports 25 or 80 (as suggested by DNS entries) I never get a response.
Is this on the end of a DSL or cable-modem line?
