you are confusing
- the stage at which a check is done (smtp_recipient_restrictions,
smtpd_client_restrictions, ...)

- the nature of the check (check_client_access, ... reject_rbl_client, ...)

for a starter, begin by putting all your checks under
smtpd_recipient_restrictions. here is a "pedagogic" example. (obviously,
this is not a copy-paste sample)

smtp_recipient_restrictions =
reject_non_fqdn_sender
reject_non_fqdn_recipient
#
permit_sasl_authenticated
permit_mynetworks
reject_unauth_destination
#
reject_unlisted_recipient
reject_unlisted_sender
#
reject_invalid_helo_hostname
reject_non_fqdn_helo_hostname
reject_unknown_reverse_client_hostname
#
check_recipient_access  ${db}/access_recipient
#whitelists
check_client_access ${cidr}/access_client
check_client_access ${db}/access_client
check_client_access ${dnswl}
#!notyet!permit_dnswl_client swl.spamhaus.org
#!notyet!permit_dnswl_client list.dnswl.org
#
reject_rbl_client   zen.spamhaus.org
reject_rhsbl_sender dbl.spamhaus.org
#reject_rhsbl_clientdbl.spamhaus.org
reject_rhsbl_reverse_client dbl.spamhaus.org
#
reject_rbl_client   bl.spamcop.net
reject_rbl_client   psbl.surriel.com
reject_rbl_client   korea.services.net

Its about "RCPT TO" not "Mail To:"

http://www.postfix.org/postconf.5.html#smtpd_recipient_restrictions
   "The access restrictions that the Postfix SMTP server applies
   in the context of the RCPT TO command."

Thanks Sahil

Basically What i want to check is when a mail is recieved from postfix 
if it can reject the e-mail is the sending e-mail server is in the 
blacklist rbl


smtpd_recipient_restrictions is about "Mail To:" right. So if I have an e-mail account on 
my postfix server and the spammer says "mail to" address it will still pass ? Am I 
correct?

Clarification between smtpd_sender_restrictions & smtpd_recipient_restrictions

2011-06-08 Thread Janantha Marasinghe 

Hi,

I'm a bit confused between the

smtpd_recipient_restrictions  
  &  
smtpd_sender_restrictions
I want to implement RBL on my mail server and I was thinking having the 
reject_rbl_client on the smtpd_sender_restrictions.

If someone could clarify this to me it would be great.

thanks
