Got it, but I still need to receive notifications from the website without using SMTP...Email providers just recently was required to have more strict smtp policies, & so now you'll see a high % of undeliverables, marked as spam, & email rejected by email servers.
I think I have to receive the activation code without this SMTP... I think it's something from this version of the script...
On the older versions, I didn't use SMTP because I didn't know how to configure it, and I received the activation code and notifications without problems...
