Hi Folks, I Want to Configurate Outlook Express behind ISA Server to get e-mail from ISP. Now is working properlly, but with Client Firewall enabled. I Want to work without Client Firewall. I have created a rule called "Outlook Express" with this protocols: dns query, pop3 and smtp. I disabled client firewall and didn't work. If I enable client firewall , it work. Help-me Please, Thanks Alex Decarli
