Exchange and MX Question 1

[Ladynet]

Hello

I sorry if this seems dumb but I haven't been in the tech field that long.

My company wants me to move our MX record from our Pop3 to our internal exchange 2000 server. I have read several books and scanned microsoft for help in doing so and I was just wondering if there is anything I need to do except set up the DNS?

Thank you and hope to hear from you soon

'move' your MX?
All you (or the ISP) has to do is point the MX record to the correct Ip address, in this case, the Exchange server or router/firewall, with a forward of port 25.

But, are you sure you have an MX record, as you mention POP3...

Do you know what external IP address(es) you have?

For example:
Whoever the ISP is for your business they are likely handling DNS (your DNS zone)for you. They would have given your compnay one or more IP addresses. One of these IP addresses has a A record. As an example this record states that IP 63.160.155.124 is yourdomain.com. In addition to the A record you also have a MX record. An MX record is an entry in your DNS table (zone file) that controls where email is sent for the domain name. It may look like this;

A record - yourdomain.com = 63.160.155.124
MX record - yourdomain.com

The MX record says all mail goes to yourdomain.com and yourdomain.com translates to 63.160.155.124.

Does this help?

Thanks

My external IP address to get to the internet is Through 1 company (we have 10 addresses), but my POP3 and SMPT is through a totally different company.

What I would like to do is remove our external POP3 and SMPT and bring it inhouse using the 10 IP addresses we have assigned to us

So I am setting up a DNS server and trying to find some assistance on transfer of records. In other words How, and is there anything I should be aware of?

I am planning a network design as such

router -> PIX -> DNS -> exchange -> Users
PDC
WEB
SQL

All you need to do FIRST is talk to your ISP, and ask them to create an MX record for you, on your domain name. That MX record will need to point to 1 address of your company, the one where your Exchange server will be on.

Thanks Marc

So if I understand all I have to do is call the POP3/SMPT provider and have them transfer the MX record?

Or just have the 1 company that provides internet access create a MX pointing to my exchange?

It does not matter who you call, but your ISP is the most likely one. Otherwise, the one that handles your domain name is the most logical point.
If the POP3 provider is a different one, forget about that, they have nothing to do with that then.
Bottom line, it does not matter who or where your MX gets created, so best is to keep it in one place, thus where the domain name is handled would be best.

Thanks marcs41

the thing is the company wants to pull not only exchange but the domain and web sights in-house this is why I am a bit confused on what to do

I set up the DNS but the main DNS is still outside so I do beklieve they will host the .com part and faward to my DNS should the MX record stay where the .com is hosted?

You really need to talk to someone.
This is hard to explain if you don't get the basics.

WHERE the MX is handled does really not matter, as long at it gets known world-wide. Hence the 'logical' place is an ISP domain hosting company.

Your own DNS is to server your network, not others.
Your DNS will 'steal' the DNS info from your ISP, and use that to serve your network.

There are more complex ways of course, but, for your own good, I would not go that way if you not 200% sure of what you are doing!
