Account activation email

Howdy,
I have signed up sofar 4 times with 4 separate email address's - three free providers (gmail, yahoo, hotmail) and one domain name which I own myself.
None of them I have recieved a confirmation / activation email from.
Is there something currently wrong with sending of the activation emails?
