POP Protocol not working

I have just activated the POP protocol in my brand new Small Business Server 2003.
I t is accepting pop connections but it rejects all the users, it gives me this error:

There was a problem logging onto your mail server. Your Password was rejected. Account: 'mail.xxxx.xxx', Server: '', Protocol: POP3, Server Response: '-ERR Logon failure: unknown user name or bad password.', Port: 110, Secure(SSL): No, Server Error: 0x800CCC90, Error Number: 0x800CCC92

I acces with the same credentials through web acces with no problems.
It SEEMS as if the POP isnt accesing the server to validate the users

Why don't you use Outlook and MAPI? Or don't you have Outlook on your workstations? POP is an ancient and primitive protocol. If you can, avoid it.
It may be casued by the "Username" you entered in your POP3 connector.

Verify the username as well as the password. Depending on your ISP the username is normally the part before "@". IT can also be case sensitive.

I use Outlook inside the local net.
Outside i use POP.
Anyway I activated the imap and I get the same error that the username or password are wrong:

Logon failure: unknown user name or bad password.

   Account: xxxx
   Server: xxxx
   User name: xxxx
   Protocol: IMAP
   Port: 143
   Secure(SSL): 0
   Code: 800cccd1

This is not the connector ormerodrutter, this is the protocl

The connection works fine, i connected perfectly via telnet to the ports and everything.
The user ia am using is the network user which is the same i use when i connect via OWA

the same username an password i am using to sync the with the ActiveSync and it works fine with the activesync

What format are you using for POP3 for the username?
It has to be a specific format.

Sembee,that is correct, it works with all that!!!!
is there any way to avoid putting all that ??? Is there any configuration that can be made in order to allow the users just put the username or the alias????
Thank you
Nope. That is the way it has to be put in for POP3 to work.

Sembee, last one
For "retrieving" mails it takes the format you told me, but it doesnt take it for sending.
For Sending it accepts just the name. Right?
It is really a nightmare for deploying!!!
Sending and receiving are different protocols so require the information in different formats. Not a lot you can do about it.
