Hello

How do install/enable POP3 service on Exchange 2003? I have my SMTP service working but can't figure out the POP3 part? I'm using "dynamic IP forwarding" service from DNS2GO

Thank you

Peter

the POP3 service by default is disabled....its an actual service under services.msc.

I have started this service and it's running now, how do I configure it in Exchange? My Firewall is set to allow POP3 traffic

Thanks a lot

if the service is running you just have to enable the pop3 access for the users in Active Directory Users and Computers (default is enabled)

If you're using an SBS server then you need to configure the POP 3 connector.  If not, then you will need to purchase and install a 3rd party POP3 connector (I'm not sure if there are any free connectors available).  i use this one - http://www.mapilab.com/exchange/pop3_connector/.
You then need to configure the connector to connect to the POP 3 server and download the messages.  It is very straightforward to configure.

Just starting the POP3 service on Exchange will allow clients to connect to your Exchange server using POP3.

First, you are confusing yourself (and most of us)

There are 2 things here, the POP3 service, and the POP3 connector.

The POP3 SERVICE allows users to connect to your exchange server and download mail via POP3
The POP3 CONNECTOR allows your server to download from another mail server instead of allowing direct SMTP connection

You do NOT need to purchase a 3rd party connector - SBS has it built in.

So, what is it that you are actually trying to do here?

Ideally, you should not be using either the POP3 service, or the POP3 connector.  The POP3 service is very insecure, and a weak alternative when you have RPC/HTTP - and the POP3 connector is a piece of junk, like all POP3 connectors, and should be avoided - instead, get mail delivered directly.

I'm a beginner and I'm trying to learn how to setup Exchange on my home office Wind23k (not SBS) lab server. I have "static IP service" from DNS2GO to direct all request sent to "server2.dns2go.com" to my server.

I'd like to be able to send and receive email via my exchange server, now I can only send email using my exchange server from this addres peter@server2.dns2go.com but I can't retrieve mail that is sent to this address. and get this error from the "Postmaster"

how do I set it up with RPC/HTTP?

thanks for all your help

Peter

Ahh, I must have picked up incorrectly that you are on SBS

Right, I just did some testing on your server, and it seems to be answering (well)

There are a few things though - first, you are going to need to configure your server to receive for the domain @server2.dns2go.com (which you may have already done) -> http://support.microsoft.com/kb/268838

Second, you should change the FQDN of your server from server02.mathura.local to server2.dns2go.com (assuming you can do that with DNS2GO, I have never used them). -> http://www.vladville.com/wiki/doku.php?id=change-exchange-smtp-greeting (bad link, but instructions there anyway)

Finally, RPC/HTTP is a bit of work, but well worth it -> http://www.amset.info/exchange/rpc-http.asp

What POP3 has to do with any of this, I am not sure :)

you should use the server02.dns2go.com as the outgoing server instead of server02.mathura.local

Hello

Now when when I send email peter@server2.dns2go.com I don't even get Postmasters warning that my email wasn't delivered, so could it be that my ISP is blocking POP traffic to my server?

Do I need to try setting up RPC/HTPP before I can send and receive email from OWA? I can't even do that, I can only send email from OWA but can't receive?

Thanks for your patience :-)

>>so could it be that my ISP is blocking POP traffic to my server

Unlikely, I can connect to your server.  And you are still getting confused with POP - it is not involved here at all.

OWA is setup by default - RPC/HTTP needs to be configured.

If you cannot receive in normal outlook, then you will not be able to receive in OWA - they are both effectively the same things.

The problem is that your server isn't configured to receive mail for that user.

Try creating a new user with a new email address - something like experts@server2.dns2go.com - the email addresses for new users should be created automatically by the server, then send mail to that and we will see how it goes
