email sending issue with CI4

Hi,

If you are working locally trying to send email with wamp, I suggest you to try this service during your developpement : https://mailtrap.io/
I get (a lot of) issues with email sending and the problem was not CI4 or wamp but providers resctrictive policies trying to fight against spam.
Once your app is ok, it should work as well online with your providers smtp settings.

Hope this will help !
