One thing you need to keep in mind with ISA server is that it is a
firewall, and will only allow the connections that YOU tell it to allow.
I suspect that the HTTP and HTTPS rules you have setup are for people to
talk directly TO the ISA server. Thy this: Logon to the ISA server and
see if you can surf to an SSL site. Then remove your HTTPS rule. It
should break, but normal HTTP should work.
For the outgoing mail, did you setup a rule to allow SMTP outbound?
To allow your USERS to have access to protocols other than 80, you will
need to give them access. Unfortunately, I have not used ISA server in
a while and cannot tell you where to look (sorry...) but I think it is
in some place related to NAT - Well, im not sure... but I hope the
first paragraph will help you find what you need.

http://www.ISAserver.org
We have just installed a new Windows 2000 SBS server with ISA and
Exchange. We retrieve mail from a SMTP queue using a fixed IP address.
I have 2 problems to solve :
Browsing works except for SSL sites like Hotmail and Yahoo. Cannot find
a
reason. I have HTTP and HTTPS rules setup but no luck.
Email - Incoming mail works perfectly but outgoing mail gives error-
Domain xxx is not reachable. Error 4003.
Any ideas where to find a solution. I have searched Techlink and various
places but no solution appears
