setting up email exchange server with verizon DSL

You're on the right track. The link you posted is a great guide which I have used in the past.

Find out who controls your DNS. This could be your web host if you have a website, or could be who you bought your domain name from.

1.) Decide which of the 5 IP addresses you will use for your mail server
2.) set up an A record for your mail server's IP address  example, mail.yourdomain.com
3.) point your domain's MX at your new domain name - mail.yourdomain.com
4.) contact your ISP (the owner of your IP address) in your case, Verizon set up PTR records for your IP address

To answer your original question, I found this info on the Verizon website. Their tech support number is 888-649-9500, 24 hours a day.

thank you, goban!
i talked to the verizon technician.
i gave FQDN and Static IP and he is creating PTR Record now.

now zone edit.
do you think this is right setting?

It should work IF

1.) The portion of the FQDN that is blurred out in your screen shot are the same for three boxes highlighted in red.
2.) The IP address listed as xxx.xxx.213.77 routes to your Exchange server.

I don't believe you will need the MX record for www.yourdomain.info, simply using youdomain.info should be sufficient. If you want to list a backup server, this line in the configuration would be the place to do so. Mail will be directed to the MX with the 1st priority, then to the MX with the 2nd.

youdomain.info. MX backupmailserver.yourdomain.info

You can use this website to check to see if your settings are in place: http://www.dnsstuff.com/
Use the reverse DNS lookup tool to verify that Verizon has added the correct PTR for your Exchange server. mail.yourdomain.info

thank you, goban.
is it bad idea to show all the ip address here?
or should hide for security?

i'm still having trouble receiving email from external.
do you know how to use telnet command to check?

how would i reflect the domain name to exchange server after changing zone edit?

Before you try telnet, you want to make sure your telnet session is routed over the internet and not your LAN otherwise you will get false results.

open a command prompt and run:

telnet mail.yourdomain.info 25

OR (your exchange public IP)

telnet xxx.xxx.213.77 25


You should see a response like this one

"220 mail.yourdomain.info Microsoft ESMTP MAIL Service, Version: 6.0.3790.3959 ready at  Fri, 1 Feb 2008 01:05:32 -0800"

You must make sure that your exchange server is reachable at the IP address you set in your DNS settings. If you can't telnet or ping to your IP address from the internet then you will have to find out why. Usually that indicates your router is not configured properly or you have a firewall that is blocking traffic to the server.

i could send email to my gmail account.
but when i reply, i got an error message
do you know what's wrong with it?;

Delivery to the following recipient has been delayed:

     name@yourdomain.info

Message will be retried for 2 more day(s)

Technical details of temporary failure:
TEMP_FAILURE: Could not initiate SMTP conversation with any hosts:
[mail.yourdomain.info. (50): Connection timed out]

i got this error message, when i reply from

Something on your network is blocking inbound traffic to the exchange server. At a minimum, inbound and outbound TCP traffic on port 25 must be allowed to pass to the exchange server. If you want users to be able to access their mail outside your LAN, you will have to open other ports as well.

i think i set up router forwarding port 110 and 25...
how would i diagnose exchange server? any tool? command line?

Use my telnet instructions I provided to test your connection. Try running the command from :

LAN
telnet [your.local.ip.address] 25

Internet
telnet [your.public.ip.address] 25

Locally on the exchange server
telnet localhost 25

If you can get a response from SMTP on your Exchange server either locally or from your LAN but cannot the get a response from the internet, then you probably have a problem with your routing or firewall configurations.

Heres a link to more step by step instructions for using telnet to send a test message.

i fixed the firewall. now my exchange server is working.
thank you so much.

do you know what i should do to connect exchange server from outside with my outlook?
need a firewall setting?

I recommend you use the RPC over HTTP protocol for connecting remotely using the Outlook desktop application, and use Outlook Web Access for users wanting to check email using a web browser. Both work using SSL to encrypt communication between the server and your clients without the need to setup a VPN.

thank you.
what is RPC over HTTP?
how would i set up?

thank you, goban

You're welcome, I'm glad I could help.
