Mr. Shinder, I've done your advise and its working, it denys all sites except for the allowed site. But then when my user used the e-mail, he cannot send/receive message. The error is this: The connection to the server has failed. Account: 'infosys1', Server: 'mail.laguna.net', Protocol: POP3, Port: 110, Secure(SSL): No, Socket Error: 10061, Error Number: 0x800CCC0E When I disabled the S&C I created to deny all sites and allow a certain site, the e-mail works again. What causes the problem? How can I fix it? pls. help. thank you in advance
