Can you post the message?
Also upgrade to ISA 2004
As I said, there is no need to add a hole for port 110, If the ISA client is installed on the workstation, Outlook will deliver the email.

Susan,
The email comes back and basically says that it is undeliverable.
As for the ISA 2000 client, I will verify tomorrow. Thanks for the input.

Because neither one has ISA 2004 content. There's no need to add port 110... the server will go out to the Internet. There is no need to poke a hole. What you do need is the ISA client on the workstation.
What's the error message you are getting?

Susan,
I appreciate the frustraion as I am feeling the same. The two books that I have read through do not seem to specifically address the issue. And I could not find an answer. Adding the ports did not seem to solve the problem so I wrote to this list. (books are Harry Belford's SMB Series and Charlie Russel's Windows Small Business Server 2003 - Both really great resources).
POP3 refers to the type of account that one sets up in Microsoft when adding a new account (like IMAP, HTTP.... See Adding a new account in Outlook). It uses POP and SMTP to recieve and send respectively.
I have several SBS 2003 Servers and never have had this problem. I am baffled as to why this installation has this problem. Your answer of adding a port is one that I thought was obvious and I already tried it.... However, maybe I did make a mistake when adding the port. I have made other changes since then. I will try it again.
Thanks,
John

Hello?
Sir?
Connect to internet wizard pokes the holes for ISA, if you need additonal ones just 'add a port' You don't open up pop 110 to "send" mail.
You probably have the ISA client not installed on the workstations don't you?
Would you guys stop reading the third party ISA web sites and read a SBS book instead or even crack open the SBSpremiuminstallsteps.htm on the cdrom?
Sorry to be mean but it just seems like when folks install ISA they are not reading the how tos on the cdroms.
Don't disable the firewall you are putting yourself at risk if you don't have another hardware firewall external to the box.

I am trying Several things here to fix and test the problem and it appears when the Firewall is on that I cannot send/receive POP3 Email. If I disable the firewall in the CEICW, then I have no problems. The clients can get to the Server put cannot get past the Server. I have Exchange downloading email and it gets to the client email box. Since we have multiple addresses, we are also using POP3. For some reason, exchange will not send email through one of the Domain Hosting providers. Again, the POP3 Email will not send/receive when the Firewall is enabled.
On a side note... The ISA does not seem to have a completed template that fits my usage needs as there seems that there should be a setup to have appropriate ports open for email, RWW, HTTP, etc... It would be nice if MS created a wizard to allow on/off these options.
Thanks for any help that you can provide,
John
