iis smtp nntp: I have created a Windows Server VM as follows:

2 network adapters:

1 NAT with host PC so i can talk to WindowsUpdate...disabled by default
1 MS Loopback with fixed IP 10.50.50.1

AD is installed with users defined, ,with IIS and SMTP installed. Client is
Outlook 2007.

When I create an eMail message for sending - the dotEML message correctly
goes into the default SMTP Drop folder but after a couple of minutes/seconds
- it disappears...

but where to - it should not be going off to the "ether"net...

Surely the message should stay there until a POP3 Receiver pulls it.

Have I defined my "networks" correctly? Can anyone help please?

Many thanks in advance,
regards
