need to set postfix to reject incoming mail where recipient is not in my list of company emails
(no, there is no local delivery, server acts as MX for company domains)

this is the part of main.cf which is questionable

smtpd_recipient_restrictions =
permit_mynetworks
reject_unauth_destination
check_recipient_access hash:/etc/postfix/odobreno
reject


file odobreno contains list of addresses that should be valid in rcpt to command

user@domain OK
user@domain2 OK

and so on...

problem is that I can't test this on a working server .
when I telnet from localhost any rcpt to works...

current mailing system is like this

MX
transport_map
|
|
|
qmail_on_hosting_1 qmail_on_hosting_2 qmail_on_hosting_3

i got the list of emails from hosting servers in one file and I need postfix to check it...

hope that I made a good explanation of the stuff that I need

This may be a stupid question but have you left white space in front of your smtpd_recipient_restrictions arguments?

So instead of:
it should really look like:

actually it is like that... forum script translated blank spaces to ""

how could I test it ?
