process of hosting MX records

[736xl]

It has been a while since I've done this. I would greatly appreciate if anyone can tell the process.

The ISP provider generally will host the MX records
I don't remember where I need to go to point to them in exchange. Is there anything else on the router, or DNS that I need to modify for this to work?

Thanks much.

You need to verify that port 25 traffic is forwarded through your firewall to your Exchange server.

Once that's done, test access from outside to your Exchange server using telnet.

Create an A record in your public DNS for your public IP address. Call it something like mail.yourdomain.com.

Have the ISP point the MX record to that A record.

As for "pointing to them in Exchange", you don't. MX records are for inbound email only.

Pat,

Thanks for your help. My confusion is that hosting of our domain and our ISP are two different conpanies. Does this matter? Whom should I registrering the MX records with? When you say public DNS you mean local dns?

thanks a bunch.

Your PUBLIC DNS is where your MX records are kept. That would be where ever your domain name is hosted. Not your internal DNS.

Pat,

One more question. I've got the DNS portion. Is there anything in Exchange I have to modify?

Thanks again.

Not related to MX records. As long as your Exchange server is ready to receive on port 25, and the firewall is forwarding that traffic to Exchange, you should be all set.

There are, of course, other things to look at, including recipient, connection, and sender filtering. But those aren't related to MX records.

Pat,

Any chance you could give me some more info on these other things? As of now our office is routing between local exchange and pop3 mailboxes. This is terrible for many reasons and I would like to change it. I've dealt with exchange5.5 and 2000 a while back. Exchange 2003 is a bit new. If you can point me to what other issues I need to be aware of, I'll look them up.

Again thanks much. Stars to you

I don't see any stars!

I'm not sure I understand what you're asking. Are you saying you're using POP3 mailboxes as well? If so, get rid of them!

pop3 are not local. internal exchange mail is routed to an ISP pop3 account (yes everyone has a pop3 account).
I will start discussing with the ISP to host our exchange records but I want to make sure before I kill all all pop3 accounts, local exchange will route email correctly.

You've mentined that there are other things to consider, other then MX records. I need to make sure I go through all of them so that exchange will function properly when I am done.



Thanks again

Hello,

I am in a similar position as you. Did you get it sorted in the end? Was it very difficult?
