	Many ISPs now block "pass through" SMTP -- especially original port 25
SMTP; only "their" server is permitted to connect to outside hosts.

	If all your destinations are using TLS with alternate ports, you might
be okay, but if the mail is being sent over port 25, it won't go anywhere.

	WinXP Pro supposedly contains an SMTP server as part of the "Internet
Information Services" (IIS6) suite (optional component activated via
control panel). Win7 Pro seems to have removed that (SMTP) component from
IIS7.
