Logon Error for incoming mail server (POP3) by connect to Exchange 2003

I have a Small Business Server 2003 with Exchange 2003. All standard setup procedure.
Outlook Web Access is working, Exchange over HTTP is working too.
Now I would like to get the POP3 access working as well.
In the Services POP3 Service is running.
When I try to connect with a POP3 Mail account setting from Outlook 2003 I get the following result:

Establishing network connection: Completed
Find outgoing mail server (SMTP): Completed
Send test e-mail message: Completed
Find incoming mail server (POP3): Completed
Log onto incoming mail server (POP3): Failed

The Error is:
Log onto incoming mail server (POP3): The specified server was found, but there was no response from the server.
Please verify that the port and SSL information is correct. To access these settings close this dialog, then click More Settings and click on the Advanced tab.

I checked all settings on the server... everything is just as standard.

Is there a firewall on the network?
are you using the correct port (usually 110)?
are you sure that the pop3 server (as opposed to the pop3 connector) is running?

Standard SBS2003 Firewall,
Port 110
Just checked again... Microsoft Exchange POP3 Service is up and running.
jonesy2kCommented:
Is port 110 allowed by the firewall?

try manually telnetting to port 110
telnet mailserver 110

and see whether you get a reply...

Just tried that...
I get a blank screen with the cursor flashing... when I try to write anything it is not displayed... only the cursor moves to the right
but I don't get any error
?

Small step forward...
I added the POP3 port to the SBS2003 Firewall and I'm able now to receive E-mails using POP3 account on the Outlook2003 Client.
The telnet also returned now a different screen:

+OK Microsoft Exchange Server 2003 POP3 server version 6.5.7226.0 (server.domain.com) ready.

I guess this is ok...

Now I have a different problem on the outlook client...
The 'Test Account Setting' is without errors and I can send mails to someone on the exchange server.
But when I try to send a mail to an external mail address I get the following error:

None of your e-mail accounts could send to this recipient.

Why?

I think you need to check your DNS setting on the SBS server.
jonesy2kCommented:
I think you'll find that the problem is actually that you are not authenticating to your outgoing mail server...
You'll need to either authenticate with your username and password, or alernatively, on the smtp virtual server in exhcnage, configure it to allow relaying from your IP address (this is disabled by default).
The first way is the better option.
