The delay_warning
I’d like to set an aggressive warning delay but only warn postmaster, not the
sender. It appears delay_warning_time is used for both sender-warnings and
notify_classes, so there doesn’t appear to be a way to do this.

The built-in defaults are:
Something else strange, i have been trying to replicate this situation
using a dummy server to send my server a message with From: and To:
using the same invalid address. This time i got two reject messages in
the logs:
NOQUEUE: reject: RCPT from example2.com[IP]: 550 5.1.0

I observed a strange (to me) behavior and id like a better understanding
of what is happening.
I have smtpd_reject_unlisted_recipient = no
I do not have reject_unlisted_recipient in any of the
smtpd_*_restrictions
I have a milter that checks the rcpt address against SQL and returns a

I want to challenge this assertion. Postfix regularly artificially adds
line breaks and even truncates responses based on an arbitrary length
picked by the programmer.
:
550: 5.5.1 Address u...@example.com does not exist
5.5.1 This is the text returned from main.cf:smtpd_reject_footer
That does not match the server response.
What do you mean does not match server response? Are you talking about
"Address %s does not exist"? It is the response im

Hi
I have one question.
I use in postfix map like:
sender_bcc_maps = proxy:mysql:/etc/postfix/mysql_sender_bcc_maps_user.cf
My scenario
server mysql is galera (3 nodes +haproxy) like:
-nod1
-nod2
-nod3
balance roundrobin - works fine
but when I set state to DRAIN (node 3) connections exists
