Probably trivial, but I am in holiday and using an emergency connection,
so I ask instead of searching again.
Problem: a website in a multidomain server is spamming probably due to a
bug in the site code.
The owners are also in holiday; I can't stop the website; I can't stop
postfix :-(
All mail are from or to an address like s...@domaincustomer.com
I need to block these mails
Tried http://www.ericmichaelstone.com/?p=4382 and similar using
smtpd_sender_restrictions = check_sender_access hash:/etc/postfix/sender_access
smtpd_recipient_restrictions = check_recipient_access
hash:/etc/postfix/recipient_access
Added
s...@domaincustomer.com REJECT
to both files.
but seems not work for local sender.
Where is my mistake?
Thanks, B.
