Dynacmic DNS and Exchange

[pQi]

Hello Everyone,

Hope someone can assist on setting up a new exchange server.

I have been asked to setup and exchange server with a dynamice IP at the router level instead of using a static IP address.

Can someone please tell me if this is possible and can someone help me as to what steps I need to take to move forward with this request?

Any information would be greatly appreciated!

Internal / private or external / public?

 

[pQi]

it would be external / public

It is certainly possible.

You do not some dynamic DNS tool, like the one from

http://www.no-ip.com

or

http://www.dns2go.com

These tools check and update your current IP address to their servers, which allows you to use something like yourcompany.dns2go.com to point the world to your server.

More choices:

If you don't want to do that, you can also leave all mail at your ISP, and poll with a POP3 tool like PopCon to get the mails into your server.

Just for your information I've heard that a few ISP's are now blocking any email from SMTP servers with dynamic IP addresses.

They cannot just do that, there is NO difference in sending a mail from a client such as Outlook, or a server.
They can see it if they want, if they look at the headers, but that is a questionable behaviour on their part. If my ISP would do THAT, they would be gone very fast.

Of course, if you start sending hundreds of mail in one go, they may think you are spamming.

Overall, I really don't think any decent ISP would block you for that, if they do, switch.

I believe it is referring to the smtp server IP address itself, so whatever smtp server your using ie smtp.myisp.com in your Outlook client needs to have a static IP address.

The only time I see this being an issue is if your running your own mail server out of your basement using the dynamic IP provided by your ISP.

If you set your firewall to only show your WAN-IP in any traffic, there is no way they know the difference (except as mentioned above).

Besides, I really don't quite get the point. Your 'SMTP' server, i.e. your Exchange server, sends out mail just the same way Outlook does.
Unless you mean it uses it's own DNS to send directly to all domains.
If that is the case, set your server to use SmartHost and point it to your ISP's SMTP server, they won't know the difference ubless they ivestigate manually.
