Exchange Server

By masoodsharif ·
We are a group of MCSA and we are trying to install and configure Microsoft Exchange Server 2007 at our own. We are succeeded and at this point we are able to send and receive mails locally. But we are still unable to send and receive mails outside LAN.

Our Scenario consists of
1. One Domain Controller + DNS
2. One Exchange Server
3. One Client
4. One ISP router with fix public IP.

We have registered a domain name with strangerz.net and created A and MX record for our domain with SMTP port open.

What we need to do further for sending and receiving mails

Shall we connect our exchange server directly to the internet or our domain controller.

Do we need to configure our local DNS server for mail records.

where did you create the records?

by CG IT In reply to Exchange Server

hopefully, you created them on your domain name registrar authoritative name servers for your domain name, and have those records point to your public address. then it's a matter of waiting the time to live period for the record change to take place on the authoritative name server for your domain name.

On yoursdomain.com

Records are created on yoursdomain.com
all the records (A, MX, PTR) are verified by mxtoolbox.com

What we have to do with our local DNS Server.

Here is my nslookup result:


> set q=a
> strangerz.net
Server: INFINITY.mobilinkinfinity.local
Address: 192.168.2.1

Non-authoritative answer:
Name: strangerz.net
Address: 119.160.61.174

> set q=mx
> strangerz.net
Server: INFINITY.mobilinkinfinity.local
Address: 192.168.2.1

Non-authoritative answer:
strangerz.net MX preference = 10, mail exchanger = webmail.strangerz.net
> set q=ptr
> 174.61.160.119.in-addr.arpa
Server: INFINITY.mobilinkinfinity.local
Address: 192.168.2.1

Non-authoritative answer:
174.61.160.119.in-addr.arpa name = host-174-net-61-160-119.mobilinkinfinity.

typically the domain name registrars name servers

by CG IT In reply to On yoursdomain.com

are the authoritative name servers for the domain name you purchased from them, or you transfer that authority to another company or your own DNS servers.

Those authoritative name server must then have records that specify that your domain name resolves to your public IP address.

Without that, a whois query won't be answered.

you left out NS1 and NS2

by CG IT In reply to Yes we have

so I'll leave it up to you to do some googling [work] and find out what importance does NS1 and NS2 have in authoritative name servers for name resolution to IP address.
