Thanks for the quick response but i think i have found what are causing
Hi to all, my problem is this:
i have on esmtp headers advertisement DSN enabled; when some domain
request DSN to my system correct response through bounce.cf template is
sent to sender but in r4esponse i receive this:
18.104.22.168 failed after I sent the message.
Remote host said: 550 5.7.512 Access denied, message must be RFC 5322
section 3.6.2 compliant and include a valid From address
Someon can help me to resolve this issue, if it's an issue because i
think that DSN must contain empty return-path.... Am i wrong?
Postfix sends a notification message like this:
From: mailer-dae...@porcupine.org (Mail Delivery System)
It appends the domain with default settings for append_at_myorigin
append_at_myorigin = yes
local_header_rewrite_clients = permit_inet_interfaces
If you have disabled that, then you will have to provide bounce
templates with a fully-qualified sender address.
i suspect that sender use Office365 service for sending mails.
