Changing a Username and Email Address
(Windows & Exchange) KB ID 0000698 Problem This was asked on Experts Exchange this morning, and so I thought I’d get it documented.

Exchange – Are you an Open Relay?
KB ID 0000087 Problem When Email was a new medium, pretty much all mail servers were open relays, and nobody really cared, after all if someone in Nigeria wanted to relay mail through a college server in Manchester then why shouldn’t they?
