    Hello,

    I am learning how to control spam on this ISPConf3 server and tightening as far as it can go. (I received 9852 spams in 24h)
    So I decided to apply "Spam Control For Postfix" Howto with greylisting.
    It works fine although I had to modify a bit the install for opensuse 11.4 64 bits.

    My question:

    As per this Howto, the main.cf is modifyed with "smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, check_recipient_access mysql:/etc/postfix/mysql-virtual_recipient.cf, reject_unauth_destination, check_policy_service inet:127.0.0.1:60000, reject_rbl_client zen.spamhaus.org, reject_rbl_client smtp.dnsbl.sorbs.net, reject_rbl_client bl.spamcop.net, reject_rbl_client combined.rbl.msrbl.net, reject_rbl_client multihop.dsbl.org, check_recipient_access regexp:/etc/postfix/spamtrap, permit"

    Why does it end with "permit" ?

    BTW, no more spam so far. that machine start to have less constrains. Great tutorial.

    This "permits" all emails that have not been blocked by one of the previous filters (i.e., all emails that should not be spam).
