Thank you for looked at my problem. The reason for too many emails might be that my main domain and my subdomain send emails for confirmation on registration. This is x3 emails for every registered in my site: one for "confirmation" / one for "thanks for registering" / and one email that is sent to my mail. And yes, I think I can turn off these functions on my site. Please unsuspend my account, i will fix this problem. Regards
