Oulook cannot access Pop Server

[Corr]

Hello,

I currently have a Linux firewall and an ISA firewall. The ISA is new and I want it to be the primary and the only one. Everything seems to work fine when both are up as far as Web and Email goes, But when I took down the Linux firewall no one could access the Pop server from Outlook. (Remote Pop server by the way.) I created a protocol rule that allows Imap, POP3, SMTP, and DNS Query to allow Outbound. All clients are SecureNat or Web proxy. I'm still new to this system. Also the browser points to the correct firewall and I even tried setting the default gateway in the TCP/IP properties of some clients, but no success. Anyone have any ideas why this is so. Any help is GREATLY appreciated. I should also be able to answer any questions you ask me regarding the system setup.


Thanks,

John

Hi,
ISA access policies are applied in this order:
1. protocol rules
2. site and content
3. IP packet filters
4. routing rules

Check your protocol rule for POP3 and SMTP are set to allow any request.

Check corresponding POP3 and SMTP IP packet filter local port is set to allow all local ports.

Check application filter for SMTP and POP intrusions are set correctly.

Hope this helps.
