Nice to see that I'm not the only one with this problem.  I have a very
similar situation.  ISA on the Exchange box (currently, I'm waiting for
my new server to come in, then exchange and ISA will each have their own
machines), External POP client can send e-mail, but can't receive.  Have
protocol definitions, protocol rules and everything else regarding ports
110 and 995 wide open both directions, but no mail.  Have verified that
POP3 is working inside the internal network (just to check), but I'm
clueless as to what else needs to be done.

Any suggestions?

Subject: [isalist] POP client problems

I've asked this before, and I have been trying to find out what the
problem is but I can't find a solution.
I have just set up ISA on a standalone Server.
I have published our Web, FTP, and Mail.  
Internally everything is working.
Clients behind the ISA Server can send and receive mail, web browse
etc..... without any problems.
The issue that I am having, is that I am dialing up with a test machine
to see if I can send and receive e-mail using a POP Client. I have an
Exchange 2000 Server behind my ISA server.
I can receive mail from our server, but when it is trying to connect to
send, it gives "unable to connect to server".
I have the smtp service published and it is running on the Exchange
server. I have followed Toms' article on "ISA Server SMTP Server
Support". And allowed outbound access to the smtp server port TCP 25.
Do I have to allow inbound on the same port as well?
Is this what I am doing wrong?
Can someone please help?  I've been trying to get this thing working
without any success.
Thank you,
