I am using Moodle 3.9. When adding a user ( or users using CSV file) with the 'Generate password and notify user' option checked, the welcome email with the temporary password is not sent from the noreply email given at Site administration > Server > Email > Outgoing mail configuration. It is sent from the email id used in the SMTP configuration ( this appears in the 'from:' field). The noreply address given appears in the 'reply-to:' field. In case the email supplied by potential users is wrong, all these welcome mails bounce back to the real email of the admin. Is there a way to change the 'from:' field of the automatic emails to the noreply address.
Also, what is the correct settings to be given so that the admin email is not exposed in the emails generated due to forum posts of the participants.
