Setting up SMTP

[robinsdale]

In the IIS Manager -> Default SMTP server -> Properties dialog, on the 'General' tab, the recommended settings for IP address is (from the combobox) "All Unassigned" - the appropriate setting, I was told. In that combobox are two other possibilities, my PC's IP address: '192.168.0.1' and what I assume is an external IP address which I assumed to be where the mail was meant to be coming from (POP3 server??), but the address in this popup:
144.136.147.234

doesn't match the ping'ed address of the mail-hub:
C:\>ping mail-hub

Entering in the following in the browser address

http://144.136.147.234

got me to a network login dialog, to which no password worked, certainly not the ones issued to my by Bigpond, my ISP. Why is this IP address in the SMTP popup list? Is this normal? Shouldn't it be the one associated with mail with my ISP? Can it be changed?

Thanks so much,
Robyn

In reading some of the other posts, I found a recommendation to issue a ipconfig at the command prompt. This revealed that the number I mentioned about is indeed the IP address of my ISP - it also revealed that there was a valid DNS suffix. My gateway computer does not have DHCP enabled, neither did it have a primary DNS suffix, but does have the following:
Host Name . . . . . . . . . . . . : netserver
Primary DNS Suffix . . . . . . . :
Node Type . . . . . . . . . . . . : Mixed
IP Routing Enabled. . . . . . . . : Yes
WINS Proxy Enabled. . . . . . . . : No
DNS Suffix Search List. . . . . . : qld.bigpond.net.au
This Win 2000 Pro box, then, should be able to receive mail in the \Inetpub\mailroot\Drop\root folder, I should think. Anyone have any idea what I'm missing here?
Cheers,
