Is this domain hosted on your network or something, or is it a domain and email from say godaddy or one of the other web/email hosting companies>

Excalibur86 · Sep 4, 2014

its hosted in my network , looks like ivp6 is not correct

???

boosted1g · Sep 4, 2014

Stupid question, did you port forward the router to your email server for inbound smtp?

boosted1g · Sep 4, 2014

Aso are you using a dynamic dns service or do you have a static IP?

Excalibur86 · Sep 4, 2014

its static , i did port forward 25 udp/tcp but still the same

boosted1g · Sep 4, 2014

And this all worked just fine before changing the router?
Also are you certian that you used port 25 for smtp (that is the common port, but 587 and others are sometimes commonly used.
Where you using ssl/tls?

boosted1g · Sep 4, 2014

Ok, lets start with making sure you can get through to the router.

Go to this site, input your domian name and port 25 and see if it gets through to the router.

wich site please ??

boosted1g · Sep 4, 2014

Ohh sorry,

Excalibur86 · Sep 4, 2014

Success: I can see your service on on port (25)
Your ISP is not blocking port 25

boosted1g · Sep 4, 2014

Are you using IPv6 on your internal network?

Did you set your DHCP server settings on your router so that your statically assigned computer address is not inside it?

Excalibur86 · Sep 4, 2014

i aded this ports forward
1 HTTP 80 80 80 80 192.168.200.1 (working for my http)
2 Smtp1 25 25 25 25 192.168.200.202 ( i modify that ? )

Excalibur86 · Sep 4, 2014

the server has static ip ipv4 :

192.168.200.1
255.255.255.0
DG 192.168.200.50

Dns : 192.168.200.1

boosted1g · Sep 4, 2014

Did you set it up to have multiple IP addresses for your one ethernet adapter? It shows refered addresses of .201-.205

Also do you need ipv6 for your internal network? IPv6 is necessary for internet addresses as there are more connections in the world then there are possible IPv4 addresses. Now for a local network you would need more then 4.1 billion devices to exced the IPv4 limit.

boosted1g · Sep 4, 2014

Try steps 1 and 2 of this link if you are ok with dissabling IPv6 on the server.

boosted1g · Sep 4, 2014

Once you do what I listed above and set your Port Forward for smtp from 192.168.200.202 to 192.168.200.1 it will hopefully work.

Excalibur86 · Sep 4, 2014

you think guys thats coming from ipv6 ? because i dident setup that the first time ...
the os is windows small server 2011 ... im gonna try to remove the ipv6

boosted1g · Sep 4, 2014

Smal business server 2011 or windows home server 2011??

You can also try just uncheckng IPv6 in Adapter Properties

Excalibur86 · Sep 4, 2014

ok i removed ipv6 but now the port 25 its say closed ?? how i can change it in my server to another port ?

boosted1g · Sep 4, 2014

What is saying port 25 is closed?

Did you restart your computer after removing ipv6, and then did you do the command prompt commands to rest TCP/IP stack?

Excalibur86 · Sep 4, 2014

yes i did :
i changed DisabledComponent was 20 changed to FF Restart computer
reset tcp/ip stack restart computer
i added manually ip local for server 192.168.200.1
the port 80 is open but when i check my port 25 its say closed Port 25 on x.x.x.44 is closed! - Connection timed out

boosted1g · Sep 4, 2014

Did you change the port forwarding on the router to your server IP address?

Put up an ipconfig /all list agian.

Excalibur86 · Sep 4, 2014

i chenged the port forw in router :

1 HTTP 80 80 80 80 192.168.200.1
2 Smtp1 25 25 25 25 192.168.200.1
