In the Outlook Express Accounts manager: pop3: 192.168.10.10 smtp: my.smtp.mail.server Account Login: test Account Password: 1234 Mark 'My server require auth' right too? When try to connect to mailserver receive the error: Code: Problem when try to start the sesion on the server. The server rejected your username login.
