How and where to use the templates?

Thanks, for asking

Thxs, i spend some time to find :

Navigate to Administration \ Configuration \ System \ Mailer

but I do not have that.
I checked permissions but I'm super admin
Also If I enable the Drupal Swift Mailer module nothing is changed.

I found other paths but none of them is displaying the screen : Mailer Policy like mentioned in the documentation..
Any suggestion what should be done?

Which version of Varbase?
Varbase 10: Only Symfony Mailer → the module - 📌 Add symfony/mailer into core RTBC - the library was committed to Drupal 10.2.x
Varbase 9 : Default to use Symfony Mailer, ( The use of Swift Mailer → was deprecated - Only for old sites to have a smooth Switch From Swift Mailer to Symfony Mailer )

Switch between the documentation
