when soemone Make account on my forum then There's a big issue of many users not receiving their activation emails in my forums. They've checked inbox and spam but still nothing. i pay $5 for solved this issue thanks
The issue may be with the host. Does your host have a limit for how many emails you can send in a day?
I dont hink it is a but , i'm sure you dont have php mail activated on your hosting , try to ask them to activate the php mail funcion on your hosting account, or you can use smtp!
