Welcome to IWETHEY!

New OK. maybe I've both misunderstood and overreacted
On the other hand, that message was the 1st time I've seen all the pieces put together.

I was under the impression you had no MX records and you were not running an inbound server.


My mail address DOES have an MX record in register.com's DNS. However, it's an external DNS to my provider; check the IP address and it doesn't show up as the name(s) I use.


We've just hit into "who owns the block"? Who is the authoritative DNS server for the block?

In order to do a reverse DNS, you've got to start with that.

Who's name DOES show up when you do a reverse?

I seem to recall when my company does some complex DNS setups, dealing with other company's servers being dropped into our address space, we needed to setup some type of DNS delegate structure to allow it to work. Got nasty.

Let's get back to the email server conversation.

Your's connects to the other one.
Him: Who are you?
You: mail.whatever.net
Him: (does reverse DNS) - Liar! <breaks connection>

This is a perfectly reasonable response.
New Well - that's the way I understood warhead to work
Who's name DOES show up when you do a reverse?

The address that's returned is: dsl027-160-095.atl1.dsl.speakeasy.net. In an experiment, I set the MX for imrics.net to point to it (after setting sendmail to accept mail for it), so that's what's in the MX record right now. Once upon a time, though, I used to point it at imrics.net. I left the dsl027* address in place because it seemed more logical to me. Either way seemed to be effective.

And - thanks if you can give me any insight (or help in connecting to warhead) - as you know, I don't claim any big expertise in this stuff... All I have is my own experience to go by - and I don't do this stuff professionally.

Imric's Tips for Living
  • Paranoia Is a Survival Trait
  • Pessimists are never disappointed - but sometimes, if they are very lucky, they can be pleasantly surprised...
  • Even though everyone is out to get you, it doesn't matter unless you let them win.


Nothing is as simple as it seems in the beginning,
As hopeless as it seems in the middle,
Or as finished as it seems in the end.
 
 
New Is this a personal or business account?
And is the address a static or DHCP one?
New Personal -
Though one of the forwarders is professional. Speakeasy doesn't care, as long as you're not spamming or doing anything illegal. The address is static...

New You need to pay speakeasy more money to make it work.
I've got a business account with them.
One if the features of a business account is DNS setup.

Without the DNS setup, you CANNOT get a reverse DNS to work since no matter what you say at register.com, if the ISP does not delegate the addresses it is not the authoratative name server, which means no one knows to go to it for the address.

Bottom line: You work by accident. No matter how well, it is still an accident.

But: You may be able to kludge it. Some more.

Change your system name to match the reverse DNS entry. Give it a shot.
New No surprises.
I understand that a reverse isn't going to work. I don't think it COULD work for my setup. That's why I don't understand how it can be a common check for mailservers though. It isn't logical (to me anyway) that I can have no trouble with virtually all mailservers when reverse DNS won't work for me, if even a sizable percentage were using it.

Interesting idea about the system name though. Gonna try it.
