I'm just wondering if it's possible to use check_client_access in postfix_recipient_restrictions.cf, like: (used postmap to create the db)
before any rbl check and greylisting?
I have placed one but seems not working, I'm not sure if I entered the correction information like:
.example.com REJECT with message
.example.net REJECT with message
.example.com and .example.net and xxx.xxx.xxx.xxx can still send e-mails to the users...
Any idea doing it correctly?
Thanks in advance.
