where to put RBL settings

[linuxguy]

dear list,

 

Currently I have these rbl settings in main.cf:

 

smtpd_client_restrictions = permit_mynetworks,

        permit_sasl_authenticated,

        reject_unauth_destination,

        reject_rbl_client zen.spamhaus.org,

        reject_rbl_client bl.spamcop.net,

        permit

 

Is this the right format?

But I saw others use these forms:

smtpd_recipient_restrictions =
        permit_mynetworks,
        permit_sasl_authenticated,
        reject_unauth_destination
        reject_rbl_client zen.spamhaus.org,
        reject_rbl_client bl.spamcop.net,
...

 

 

So my question is which directive to put rbl settings in?

"smtpd_recipient_restrictions" or "smtpd_client_restrictions"?

 

 

Thank you.
