Question about Exchange

[Genx87]

I have a couple of spare computers around so I decided to fire them up with server and play with AD, DNS, DHCP, ect ect.

After I got done playing around with two domain controllers. I rebuilt them and tested how the software raid works and how a system state restore works. Fun stuff and glad I have the resources to play around with this.

Back to the point of this thread. I got the AD up and running and then setup the 2nd server with exchange 2003 trial from MS. Ok everything went smoothly except my domain isnt registered so I can send emails from the box but cant recieve because the emails from the domain which isnt registered.

No biggie so I go and get a freebie from dyndns.org.

The question I have is there a way to setup exchange to handle incoming and outgoing email for a domain like exchangetester.dyndng.org?

I have searched through the MS technet but it seems like you can do it but nothing really helpful. And yes I have port 25 open. But another question I have is does the port need to be open for the actual exchange box or the AD controller?

I have it open for both atm.

This is something I wanted to learn but didnt have the resources to do it until recently. I have been blowing up those two boxes for the past 3 weeks hehe. Takes about 2 hours to rebuild so no biggie. But learning a bunch and any help on this is appreciated.

Ok toying around with it I did get it to work by adding a recipients policy to the thing and changing the AD's account email to the domain I registered.

However I am curious how to get more than a single domain working here. It seems like it is very tied to AD which may make it tough distinguish multiple domains?

you can install exchange to your domain controller, and then set it up to receive email sent to blah@domain.dyndns.org no problems. It is all done through ad, users and groups

Just go in Users and Groups and you'll be able to add whatever email addresses you need. I have something like 7 Internet email addresses pointed at my Exchange mailbox.

You just need the SMTP port (25) pointed towards your exchange server. The AD server, if seperate, doesn't have to be exposed to the internet.

yeah MS recommend you don't have your domain controllers exposed to the internet, but most small business I know can only afford one server, so it usually does it all, mail, web, terminal services, ad, etc.

Actually, the only port I expose on the Exchange server/AD box is port 443. All of my email gets filtered through Postfix and ClamAV. It blockeds a ton of spam that otherwise would make it through. If you enforce some basic rules about your incoming email, 99% of spam just gets dropped outright with no worries about false positives. I don't even need SpamAssassin.

I'm pretty sure that Exchange 2003 comes with a "Pop Connector" to allow Exchange to operate as a typical Email client (to your normal ISP mail account).

It goes out to your ISP mailbox and sucks down the mail (according to the schedule you establish), then your local client connects to Exchange and gets the mail from there.

Check it out. It "fer sher" comes with the Small Business Server Premium Edition (that's what I use), but I believe it now ships with all Exchange 2003.

FWIW

set up your dns zone
set up a and mx records
in recipient policies put in the the name of the domain you want to receive mail for. it can be different than your AD domain name
my company we have AD domain and almost 10 public domain names that we accept email for
make sure your user account has an email address with the public domain name
