PS1.7.6.4 - Location of sendMail function for welcome email?

[hamsn]

Hello,

We are not allowing the customer to set a password during account registration (it is randomly generated). Instead, we will send them the login details - email & password, by the welcome email.
This mechanism is to ensure the email entered during registration is a real one.

As of PS 1.7, passwords are no longer sent in the welcome email. So I am looking to either re-enable sending the password {passwd} or include a password reset link {url) as part of welcome email which the customer can click to set their own password. Whichever is more simpler to implement.

I want to know where the function to send welcome email resides in PS 1.7. In earlier versions it was in controllers/front/AuthController.

Any other suggestions are most welcome.

Thank you for taking time to help.

Wish you a good day.
Best regards.
