Moving black hole test to Postfix

[steinmb]

Hi
Have been thinking about moving some of the blackhole testing to Postfix
(SMTP level). In my head this is cheaper? My mail server is old so less
scanning Mailscanner have to do the better.

In /etc/postfix I changed smtpd_recipient_restrictions to:

smtpd_recipient_restrictions = permit_sasl_authenticated,
permit_mynetworks, reject_unauth_destination,
reject_unknown_recipient_domain, reject_unverified_recip
ient, reject_rbl_client zen.spamhaus.org, reject_rbl_client bl.spamcop.net,
reject_rbl_client autoblock.dnsbl

Now what? Do I remove those I run on SMTP level from my
/etc/Mailscanner/spam.lists.conf ? Doing those checks twice makes no sense.
In spam.lists.conf I find lines like:

spamhaus.org                    sbl.spamhaus.org.
spamhaus-XBL                    xbl.spamhaus.org.
spamhaus-PBL                    pbl.spamhaus.org.
spamhaus-ZEN                    zen.spamhaus.org.
SBL+XBL                         sbl-xbl.spamhaus.org.
