I have configured the php config exactly as required.
I have defined the email account to WHERE the email should be sent (proton mail).
I have defined the gmail account which is being used to send the email.
in the ‘CONTACTFORM_SMTP_USERNAME’ field, I entered the gmail address being used to send the email.
in the ‘CONTACTFORM_SMTP_PASSWORD’ field, I entered my gmail account password.
I logged into ‘https://www.google.com/recaptcha/admin’ and added the ‘SITE_KEY’ and the ‘SECRET_KEY’.
My account already has 2 factor authentication.
What else do I need to do in order to make it work?
