I know I probably sound a bit stupid here but I am having problems getting my Popmail to work. On my test network I have a Domain controller, I have a server with an ADSL connection that is also my ISA server and an XP client. The XP client has Outlook as the e-mail editor. Prior to installing ISA on the ADSL server I could send and recieve e-mail using my ActiveISP mail server settings. POP server - popmail.activeisp.com; SMTP server - SMTPmail.activeisp.com. After installing ISA, Outlook now tells me that it is unable to find the POP or SMTP server. I have created a policy that allows POP and SMTP traffic through but this not seem to have fixed the problem. Can anyone help. Many thanks
