Is your feature request related to a problem?

When sending out a password reset email for another user from Admin › Users using the advanced email settings, the email is sent out correctly from the defined publisher_email.

When the user responds to the email and resets their password, they should get a confirmation email that their password has been changed. Currently the txpEmail() function sends this from the logged-out user's email address (see txplib_misc.php lines 2391-2394). The smtp service rejects this as an unknown sender, and that email never arrives.

What is the feature?

A "Send system emails only from publisher / envelope sender" admin switch to override this 'feature' so that emails are only sent from the publisher email.

For the moment, I've temporarily patched this by duplicating the publisher_email setting and reintroducing it after the logged-out user's details have been retrieved. Then all mails are sent and received correctly.
