Setting up exchange 2000 server with no-ip

[cbr1000]

Hi
I am have great difficulty etting up an exchange server to work internally or externally. I am running exchange 2000 on windows 2000 server. when I send a message to any email address internal or external I get the following message.
Your message did not reach some or all of the intended recipients.

The following recipient(s) could not be reached:

Martin J. Knight on 14/02/2004 17:07
The e-mail system was unable to deliver the message, but did not report a specific reason. Check the address and try again. If it still fails, contact your system administrator.

The second half of my problem is I cannot receive any mail from the internet. I have my own domain (martinknight.com) which I have set up a host with

http://www.no-ip.com.

I can point the mx records to their server but not mine (I dont know which one I should be using).

If I try to set the MX record to my server (primary-server@martinknight.com) I get a 'unable to resolve host error'.

I have set up an MX record within exchange(primary-server.martinknight.com) but again dont know if this is correct. I have made so many changes now I am confusing myself(as you can probably tell from this post)

I am unsure what other details to list here so please ask for any needed info, any help would be gratefully received. I have lost all ability to receive email.

No-IP and others like DNS2Go, dynsdns etc. will not create an MX to your IP as it is not a fixed one and thus unreliable for email use.
There are soem who offer it but you need to pay for that option.

In your case, either get a fixed IP or use a POP-retrieval program like the one at:

Thanks for the reply. I am running a program called NO-IP DUC, this monitors my static IP (I am on cable so it does not change frequently) each time I am given a different IP this program updates my DNS record, so it is like having a fixed IP.

I know what No-IP does, but that is not the point. The no-ip service cannot garantee an instant update of your IP, so an MX coupled to it may fail in those cases, that is why they do not have the MX option.

Hi
NO-IP specifically lists their service to enable users to run their own mail server, using the IP udater program. NO-IP receive my mail first, and their servers run with multiple redundancy, and they forward my mail on to me via my MX record which can be set from within their host section. If my (or anyone elses) server is unnavailable NO-IP will hold the email received until it can contact my server for a maximum of five days, after which the mail is returned to sender.

That is why I mentioned some do offer it, with restrictions as you mention, and some require payement for that option.

The MX for martinknight.com points to
martinknight.com MX preference = 5, mail exchanger = mail1.no-ip.com
martinknight.com MX preference = 10, mail exchanger = mail2.no-ip.com
mail1.no-ip.com internet address = 63.215.241.221

Which indicates no-ip is your mailhandler, not you, and there is nothing you can do about that.
If your e-mail does not get sent to YOUR public IP, then you need to take it up with no-ip support.

All you have to be sure of is that your port 25 is open and if there is a router or firewall that it is forwarded to your Exchange server, which in turn has to have a recipient Policy for your domain.
You do not need to configure your MX record yourseld per se in this case, as you are not the one handling it.

Thank you for your help, I have fixed the problem of sending mail internally, and am now trying to figure out setting up a smarthost to get mail out through my ISP, and the problem of not receiving mail.
Thanks again
