Question Disable Postfix's delivery notifications (DSN)

[Hausherr]

How can I disable Postfix's delivery notifications (DSN) in Plesk?

Just as in any other Postfix setup: Postfix DSN Support.

Don't forget to disable DNS in Roundcube as well (if you're using RC ofcourse).

$config['dont_override'][] = 'dsn_default';

Have now done this as follows:

sudo postconf -e "smtpd_discard_ehlo_keyword_address_maps = cidr:/etc/postfix/esmtp_access"

vi /etc/postfix/esmtp_access:

# Allow DSN requests from local subnet only
127.0.0.1/8               silent-discard
[::1]/128                 silent-discard
0.0.0.0/0                 silent-discard, dsn
::/0                      silent-discard, dsn

Unfortunately, DSN doesn't work for me now either. I do not understand this, because I have defined my IP range an exception.
