hi there,

I have just set up an exchange 2003 server:

when i set up outlook express and try to send emails i am getting this message:

The connection to the server has failed. Account: Testserver, Server: Testserver, Protocol: POP3, Port: 110, Secure(SSL): No, Socket Error: 10061, Error Number: 0x800CCC0E

When i telnet the port 25 i am getting 220 Microsoft ESMTP MAIL Service, Version: 6.0.3790.1830 ready at  Wed, 10 May 2006 17:51:48 +0100
When i telnet net to the 110 port it can't connect.

    BY deafult pop3 services are disabled in 2003 exchange
    BY default RELAYING is prohibited in 2003 exchange server....
    so in the services section make sure pop3 is started...
    in the ESM make sure there is no RED circle on ur POP3 virtual server
    In the smtp virtual server make sure authenticated users can relay...

    go to smtp virtual server...right\ACCESS\RELAY
    here u have to be carefull....
    first make sure to check  "ONLY THE LIST BELOW" and make sure the list below is empty...unless u have web servers or other applications from inside ur network sending emails through ur exchange...
    then u check "ALLOW COMPUTERS WHICH bla bla" checking this option u allow ur external users to send through ur exchange server(like u do with ur ISP)...
    there is a bit of drawback with this option....if someone could GUESS one of ur users
    password then u will be open to relay eventhough u have relaying make sure to have a strong password and require ur users to change them occassionally....
