No registration activation email

I have filled in the registration form to activate my account but haven’t received any activation email. I have been able to get an activation email for this forum but none for my general registration. I have tried registering with 2 different emails and have not received an activation email to either address. There is nothing in my spam folders either. How can I solve this problem?

thank’s in advance.
