You have some incorrect routing going on probably within your router or dns.

That means one of two things
#1 your DNS is broken
#2 You have that entry in your local hosts file

If this happens for multiple recipients then that is your DNS that is broken
What DNS do you use (in Windows)? Try using 8.8.8.8 instead - that is Google's public DNS

[Hassan84]

I have 2 Servers, on of them is Domain Controller, and i use the DNS of the DC and the Router, which is working perfect.
I tried and change my DNS to Google's Public DNS. Nothing change same error message.

I checked firewall and everything possible and nothing change.
it's drive me crazy, Should i contact my ISP and see if there anything on their side is wrong ?

[mattg]

hMailserver isn't even trying to reach the internet, your ISP won't help

Open a command prompt on the machine with hMailserver installed on it
and type
nslookup
type=mx
hotmail.com


and then post the results

[Hassan84]

when i try to nslookup it's give me DNS request timeout.

thanks for trying to help me , i appreciate it.

[mattg]

Which shows that your local DNS is the problem

[mikedibella]

Your nslookup command syntax is wrong.

At the command prompt, type:

Code: Select all

nslookup -type=mx hotmail.com

Post the result.

[Hassan84]

Here's what happened

[mikedibella]

Breakdown of the response:

Code: Select all

Server:  localhost
Address:  ::1

This machine is hosting a DNS server, and it's DNS client is configured to use the local DNS server to resolve queries.

Code: Select all

Non-authoritative answer:

A remote DNS server other than the server that is the authority for the zone queried (hotmail.com) has responded to the query. In other words, you cannot be sure that the response is authentic for the domain.

Code: Select all

hotmail.com    MX preference = 10, mail exchanger = mx1.norelay.link.net

mx1.norelay.link.net    internet address = 127.0.0.4

Mail exchange for @hotmail.com is hosted on a server named mx1.norelay.link.net whose IP address is 127.0.0.4.

My guess is that your local DNS server is a caching server and you are forwarding from this server to another DNS server hosted by your ISP (is your ISP link.net?). Your ISP doesn't want you to host SMTP services, so it proxies MX record queries and returns the loopback address.

This is not an hMailServer configuration issue.

[Hassan84]

that what i was thinking of, i already sent them an email, will see what gonna happen.

Thank for your help.

[mattg]

Your nslookup command syntax is wrong.

At the command prompt, type:

Code: Select all

nslookup -type=mx hotmail.com

Post the result.

Thanks for cleaning up after me mikedibella

[Hassan84]

Guys,
i'm here again after a week with trying to solve the problem, contacted with my ISP and they have nothing to do with it , i tried everything guys and nothing help same issues , if anyone have any new idea please help me .

[mikedibella]

run this command:

Code: Select all

nslookup -norecurse -debug -type=mx hotmail.com.

If you see

Code: Select all

Non-authoritative answer:

in the response, look for the last line starting with

Code: Select all

ttl =

and wait at least that amount of time, then run the command again.

When you don't see

Code: Select all

Non-authoritative answer:

in the response, post the full response as text, not a screen image.

You are executing

the correct command is

I think your DNS is misconfigured but I'm not sure where. Here a couple of things to check:

1. If you are using multiple DNS servers in the local TCP/IP stack configuration, they all have to be replicas of the same set of zones. You can't use your local server as the first DNS entry and your ISP as the second. This just the way the DNS client works.

2. If you have a Forwarder configured in the local DNS server point to your ISP's DNS server, I'd try removing it or changing to Goggle's DNS (8.8.8.8 and 8.8.4.4) instead.
