Hi,
Many thanks for your answer. It is clearly the best and most precise answer I got from all the places I have posted to
I now have to check whether I can use this in my
ISP-style setup without breaking anything (it's a prod system).
As the rest of the setup is MySQL based, I hope I can setup
check_sender_access and
check_recipient_access to get the results from MySQL too.
Like : check_sender_access = mysql:/etc/postfix/check-sender-access.cf
Code:
user = bla
password = bla
hosts = 127.0.0.1
dbname = mailserver
query = SELECT email FROM view_users WHERE email='%s'
Not sure how to build the query right now.
Thanks again !
