check_client_access in postfix

[randall]

Hi all,

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)

check_client_access hash:/opt/blacklist/my-blacklist

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
xxx.xxx.xxx.xxx REJECT

.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.
