Configure a dedicated smtpd servicce in master.cf.
Then use
https://www.postfix.org/postconf.5.html#smtpd_command_filter
to
append NOTIFY=NONE to RCPT TO commands.
For example, to set up a no-bounce service on port 25:
/etc/postfix/master.cf:
:26 .. .. .. .. smtpd
-o { smtpd_command_filter =
pcre:/etc/postfix/no-notify.pcre }
Kevin
Thank you! This is exactly what
I need.

Perhaps: https://www.postfix.org/DSN_README.html Wietse I may have misunderstood the contents of DSN_README, but I don't need to turn off DSN completely. I need the DSN to not work only for those senders for whom the transport is configured to "resubmit" (pipe). In my case, I was helped by the smtpd_command_filter option, which you pointed out in your recent answer to a similar topic. Thanks for your reply.

I'm sorry, but I haven't fixed the

that the postfix does not accept messages with an incomplete

address (without the domain part)?
I guess you are trying to connect from 192.168.250.35 which is
considered local: http://www.postfix.org/postconf.5.html#local_header_rewrite_clients
so the append_at_myorigin applies.
I have configured in main.cf
local_header_rewrite_clients = inline:{ 192.168.250.25=ok }
inet_interfaces = 127.0.0.1
and connected with a telnet from the address 192.168.250.14. And
the postfix still accepts messages from the sender without the
domain part.
Did I set up local_header_rewrite_clients and inet_interfaces
correctly?
