sir, After i've configured my squid proxy, the only problem that i've encountered was when our client trying to open up their mails in outlook/eudora, the error message that would open up was "The host 'mail.domain.ph' could not be found. Please verify that you have entered the server name correctly. Account: 'mail.domain.ph', Server: 'mail.domain.ph', Protocol: POP3, Port: 110, Secure(SSL): No, Socket Error: 11001, Error Number: 0x800CCC0D". Is there anything mistake or i forget to configure up to avoid this problem on our mail. Thanks, Adam
