It happens sometimes, when I sign up for a forum or a website that I get told my e-mail address is invalid.

It looks like this: name_lastname_@hotmail.com. Is there any reason why this might be considered invalid?

It's probably the underscore before the @ sign. It's not technically invalid, but it's not especially common, and I can easily see that badly written format checkers would flag it as invalid (you're not allowed to have a full stop before the @, so they might generalise that to all punctuation characters).

Aha! That might indeed explain it. –  Simon Verbeke Feb 23 '12 at 14:16
    
Some sites limit your use of the free email accounts, because they can be viewed as throwaway accounts. –  mhoran_psprep Feb 23 '12 at 14:35
    
@mhoran_psprep: Here in Belgium, I would say the majority uses Hotmail or Gmail. Don't know about other countries. Doesn't seem like a smart move then :) –  Simon Verbeke Feb 23 '12 at 17:17
