Sends the USER command.
The USER command sends the user login name to the server. After you send the user name, you must send the PASS command to send the password for that user.
The server's response to the USER command indicates success or failure. To learn if the command succeeded, get the ReplyCode property. If the value is Pop3ReplyCode.OK, then the command succeeded. If the value is Pop3ReplyCode.ERR, then the command failed.
