To get what I promised, there were a few points to fix:
the sender of the email has to be an authenticated email address,
not the email address of the user that filled the form
the reply-to email, that is the recipient that will receive the replies,
should not change: it has to be the email address of the user that filled the form
the email address of the filler should appear in the subject line,
like here: “Callback request from info@example.com”
to facilitate the search within the messages and make management easier
