I would like to disable the delivery notification in a postfix server.
the delivery for the users (if they select the option "request a Delivery Receipt" in outlook for example and send one email to my server that the server do not reply with the "Your message was delivered to the recipient."
I already used the
smtpd_discard_ehlo_keywords = silent-discard, dsn
but it seems it works only for internal messages.
is there any way to disable it at all?
