Configure a dedicated smtpd servicce in master.cf.
Then use

append NOTIFY=NONE to RCPT TO commands.
For example, to set up a no-bounce service on port 25:

:26 .. .. .. .. smtpd
-o { smtpd_command_filter =
pcre:/etc/postfix/no-notify.pcre }

Thank you! This is exactly what
I need.

I need to filter mails with "RCPT TO: nore...@example.net" and send
them to the new daemon ?
When NDN are generated, they are send to cleanup, not throught smtpd
if I understand correctly ?

I don't have any control of recipients. When users (aka apps we host) sends mails to non-existing recipient, the mails are bounced, as usual in Postfix. Thats the trouble I try to avoid to our Postfix instances. Some teams are cleaning their mail database periodically, but the email adress came from end-users. ___ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org

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:

:26 .. .. .. .. smtpd
-o { smtpd_command_filter = pcre:/etc/postfix/no-notify.pcre }

# Bounce-never mail sink.
# Use notify_classes=bounce,resource,software # to send bounced
# mail to the postmaster (with message body removed).
/^(RCPT\s+TO:\s*<.*>.*)\s+NOTIFY=\S+(.*)/ $1 NOTIFY=NEVER$2
/^(RCPT\s+TO:.*)/ $1 NOTIFY=NEVER
