When a request for delivery of a mail is received by Postfix via SMTP, the triplet C<CLIENT_IP> / C<SENDER> / C<RECIPIENT> is built. If it is the first time that this triplet is seen, or if the triplet was first seen less than I<delay> seconds (300 is the default), then the mail gets rejected with a temporary error. Hopefully spammers or viruses will not try again later, as it is however required per RFC. Note that you shouldn't use the --lookup-by-host option unless you know what you are doing: there are a lot of mail servers that use a pool of addresses to send emails, so that they can change IP every time they try again. That's why without this option postgrey will strip the last byte of the IP address when doing lookups in the database. =head2 Installation =over 4 =item * Create a C<postgrey> user and the directory where to put the database I<dbdir> -(default: C</var/spool/postfix/postgrey>) +(default: C</var/lib/postgrey>) =item * Write an init script to start postgrey at boot and start it. Like this for example: postgrey --inet=10023 -d F<contrib/postgrey.init> in the postgrey source distribution includes a LSB-compliant init script by Adrian von Bidder for the Debian system. =item * Put something like this in /etc/main.cf: smtpd_recipient_restrictions = permit_mynetworks ... reject_unauth_destination check_policy_service inet:127.0.0.1:10023 =item * -Install the provided postgrey_whitelist_clients and -postgrey_whitelist_recipients in /etc/postfix. +Install the provided whitelist_clients and +whitelist_recipients in /etc/postgrey. =item * -Put in /etc/postfix/postgrey_whitelist_recipients users that do not want +Put in /etc/postgrey/whitelist_recipients users that do not want greylisting. =back =head2 Whitelists Whitelists allow you to specify client addresses or recipient address, for which no greylisting should be done. Per default postgrey will read the following files: - /etc/postfix/postgrey_whitelist_clients - /etc/postfix/postgrey_whitelist_clients.local - /etc/postfix/postgrey_whitelist_recipients + /etc/postgrey/whitelist_clients + /etc/postgrey/whitelist_clients.local + /etc/postgrey/whitelist_recipients You can specify alternative paths with the --whitelist-x options. Postgrey whitelists follow similar syntax rules as Postfix access tables. The following can be specified for B<recipient addresses>: =over 10 =item domain.addr C<domain.addr> domain and subdomains. =item name@ C<name@.*> and extended addresses C<name+blabla@.*>. diff -rNU 15 ../postgrey-1.37-o/postgrey_whitelist_clients ./postgrey_whitelist_clients --- ../postgrey-1.37-o/postgrey_whitelist_clients 2016-09-22 10:09:38.000000000 +0200 +++ ./postgrey_whitelist_clients 2016-10-14 01:43:55.000000000 +0200 @@ -1,18 +1,18 @@ # postgrey whitelist for mail client hostnames # -------------------------------------------- -# put this file in /etc/postfix or specify its path +# put this file in /etc/postgrey or specify its path # with --whitelist-clients=xxx # # postgrey version: 1.37, build date: 2016-09-22 # greylisting.org: Southwest Airlines (unique sender, no retry) southwest.com # greylisting.org: isp.belgacom.be (wierd retry pattern) isp.belgacom.be # greylisting.org: Ameritrade (no retry) ameritradeinfo.com # greylisting.org: Amazon.com (unique sender with letters) amazon.com # 2004-05-20: Linux kernel mailing-list (unique sender with letters) vger.kernel.org # 2004-06-02: karger.ch, no retry diff -rNU 15 ../postgrey-1.37-o/postgrey_whitelist_recipients ./postgrey_whitelist_recipients --- ../postgrey-1.37-o/postgrey_whitelist_recipients 2016-09-22 10:09:38.000000000 +0200 +++ ./postgrey_whitelist_recipients 2016-10-14 01:44:27.000000000 +0200 @@ -1,7 +1,7 @@ # postgrey whitelist for mail recipients # -------------------------------------- -# put this file in /etc/postfix or specify its path +# put this file in /etc/postgrey or specify its path # with --whitelist-recipients=xxx postmaster@ abuse@
