SMTP uses port 25 - POP3 uses 110.

But when publishing your mail server, there are options to allow POP3,
Exchange etc...

Using them would be the easiest to do.

Hope this helps you

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
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,
