Could not send/receive emails from outlook express though ISA server
Hi experts,
I have setup a domain with a child domain and clients. My DC use windows 2000 server OS. I also have a windows 2000 advanced server machine. I loaded ISA server on this machine. This pc acts as a multihome pc, where i configured two network cards. One network card for internal connectivity and the second one for internet connectivity. I assigned my gateway and ISP DNS name in the adapter which is connected to my DSL router. For the internal adapter, i have assigned one internal ip address and DNS address is loopback address (127.0.0.1). In ip packet filter option i enabled most of the required protocols. Now I am able to connect internet from all cleints. But the problem is that i am not able to send or receive emails from my mail clients (Outlook express ) or (Microsoft Outlook). Could anybody help me out as i am struggling with this problem for the last one week

If the mail is on secure sockets, the ports will be different.
There are also other issues. For Exchange and Outlook, they will try to authenticate to the smtp mail server, which, if is just port 25/110 and upstream, will not require it.
First, your network setup: what are the mail servers? do you have local mail servers as differentiated from internet mail servers?
Mail from internal servers is usually sent using user@hostname.domain.tld and not just user@domain.tld
Additionally, the mail server is hostname.domain.tld and not the smtp external server.
What are your incoming and outgoing mail servers?

Hi experts,
I dont have any dedicated email server in my network setup. Basically it is the ISP's email server i am trying to access. i have only ISA server running on windows 2000 advanced server as i told before. though i am able browse frm my clients using internet explorer, Could not download emails using outlook. I am getting a message which sounds like, client machine is not able to reach the ISP email server...

I assume your clients are accessing an internet mail server which is not in your private network.
Want to find out if it is the ISA policy issue or other issue. Are you accessing your email server thru pop3, if so are you able to get respond by telnet "email server" 110? and also port 25? from your clients?
Try to figure out if it is the ISA blocking the ports...
