Email Activation Won't Send

I just found out from a member o another trying to sign up at my forum that the email activation won't send, I ever made a test account with my alt email and it didnt send either. I was going through he Admin CP but I couldn't find anything to fix it, please help!

Was the email address a gmail one or something else??
Users & groups>Users options
New accounts activation : User
Is it User?

Yes, the email address was user, I just turned the activation off for now, and yes when I tested it it was gmail, I think the problem should be fixed now.
Thank you!
