Hello ,

Some of the questions I have are not for this forum, but most are so here is my situation.

This is my first time setting up a email service and I have a website:

abc-inc.org

The website is hosted on server in our office on a cable connection:
The static IP address 24.xx.xx.62
The DNS is: 24.xx.xx.56
All of above given by the cable company.

The abc-inc.org site is registered on a domain website with two nameservers:
NS1.Domain.com
NS2.Domain.com

In the Imail admin I have:
abc-inc.org as the host name

On the website in which the website is registered you can enter in the DNS information. The MX record is abc-inc.org and goes to mail.abc-inc.org
Two Host A records
mbk-inc.org 24.xx.xx.62
mail.mbk-inc.org 24.xx.xx.62

I can send out emails but when I try to reply back to emails I get errors.

Here are my questions:
*Why I am I getting errors should I wait for the new MX to take effect?
**Can and should I use outlook to check email, how dow I set that up? (What do I use for pop. smtp, etc..)
***In the SMTP service in Imail, should I should point to the NS1.Domain.com or use the DNS that the
cable company gave me 24.xx.xx.56.

Thank in advance
 
Here are my results, what could make it time out?

Getting MX record for mbk-inc.org... Got it!

Host Preference IP(s) [Country]
mail.mbk-inc.org. 10 24.153.154.62 [US]

Step 1: Try connecting to the following mailserver:
mail.mbk-inc.org. - 24.153.154.62

Step 2: If still unsuccessful, queue the E-mail for later delivery.

Trying to connect to all mailservers:
--END
mail.mbk-inc.org. - 24.153.154.62 [Could not connect: Could not connect to mail server (timed out).]
 
Depending on your network setup, do you have port 25 open on your firewall? If in a NAT setup do you also have the port forwarded to the mail server IP.

 

C:\Documents and Settings\Chris>telnet 24.143.154.62 25
Connecting To 24.143.154.62...Could not open connection to the host, on port 25:

I am using a Wireless Router by Dlink. I had to go the application section of the Router and open the SMTP port. Now when I go to and put in the email test part it works. The telnet part - telnet 24.153.154.62 25, did not work though. Should it? Thanks for the help!
 
I take it your using a NAT setup, are you also fowarding port 25 to the correct internal IP to?

 
Yes I am using NAT and I have NAT forward to the server static private IP address. Now I have to setup Outlook to use the information.
 
As far as i can see you still dont have port 25 open for inbound traffic so you will be able to receive mails, you should check your settings on your router again to ensure that you have port 25 open and forwarded to your mail server.

TO receive mail with out look just put the IP of you server in the POP3 and SMTP server spaces.

 
You also might want to check your ISP policies if you have configured your router right. The might block port 25. You should contact them and ask if the do any sort of port blocking.
