Check out www.isaserver.org/pages/learning%20zone.htm
There are many articles there on how to properly install, configure and
manage ISA Server.

Subject: [isalist] Send/receive mail through ISA from Unix clients not
working


http://www.ISAserver.org


Hello,

Please help me out, even if my question is stupid and answered before.
I'm very new to ISA (and this excellent list as well) but I want to
learn everything!

The problem I'm having is that I can't seem to get my Unix (HP-Ux 10.20)
clients to send/receive email through the ISA server (integrated mode) I
have set up at the office. The Windows 2000 clients have no problem with
email as they can use the Firewall Client without any problems. Normal
webpage viewing using ISA as proxy is no problem on any system, and
works like a charm. The Unix clients use Netscape's mail client, but
that shouldn't be a problem.

We currently have no internal mailservers, so I want to have my clients
to connect directly to the POP3 and SMTP servers at our ISP through the
ISA server (which has DSL hooked up to it). The clients have the ISA
server as their gateway, and the ISP's DNS servers for DNS.

I have been reading up on SecureNAT for a while, and think I have
followed all instructions on ISAserver.org to get it working, but
without any luck. Is it possible to have my clients (both Windows using
Outlook XP, and Unix using Netscape Mail) access the POP3 and SMPT
servers through SecureNAT? For the Windows clients I could use the
Firewall Client, but if not needed I wouldn't mind not doing it. Is
there a good way I can use to verify that SecureNAT is working properly?

Please help me out, as I really want to get ISA server working properly
so I can convince my managers to use for the entire company.

Thanks in advance,
