Http challange on port 25?

[webprofusion]

@jvanasco

Although all ports under 1024 are considered "well known" or "privileged", I have read that Windows does not (or did not at some point in the past) require admin privileges to bind to all those ports

Yes currently you need to be administrator to bind to those ports (or admin can allow specific users account to bind to those ports) but I'm fuzzy on the specifics and versions as well. I'll see if I can find a definitive article somewhere.
