Hi,I have a working installation of Postfix and Dovecot that works nicely. I've added SpamAssassin, which does a good job of flagging spam. Now I wanted to add greylisting to my server. Here's what I did. $ sudo yum install postgrey Increase the greylisting delay. # /etc/sysconfig/postgrey POSTGREY_OPTS="--delay=300" Edit /etc/postfix/main.cf accordingly. smtpd_recipient_restrictions = permit_mynetworks, permit_auth_destination, permit_sasl_authenticated, check_policy_service unix:/var/spool/postfix/postgrey/socket, reject Start/restart services. $ sudo systemctl enable postgrey $ sudo systemctl start postgrey $ sudo systemctl restart postfix Now Postgrey seems to be running OK. $ systemctl status postgrey ● postgrey.service - Postfix Greylisting Service Loaded: loaded (/usr/lib/systemd/system/postgrey.service; enabled; vendor preset: disabled) Active: active (running) since mer. 2019-06-19 09:39:04 CEST; 19min ago Docs: man:postgrey(8) Process: 5228 ExecStart=/usr/sbin/postgrey --unix=/var/spool/postfix/postgrey/socket --pidfile=/var/run/postgrey.pid --group=postgrey --user=postgrey --greylist-text=Greylisted for %%s seconds --daemonize $POSTGREY_OPTS (code=exited, status=0/SUCCESS) Process: 5225 ExecStartPre=/bin/rm -f /var/run/postgrey.pid (code=exited, status=0/SUCCESS) Main PID: 5229 (/usr/sbin/postg) CGroup: /system.slice/postgrey.service └─5229 /usr/sbin/postgrey --unix=/var/spool/postfix/postgrey/socket --pidfile=/var/run/p... juin 19 09:39:03 sd-100246 systemd[1]: Starting Postfix Greylisting Service... juin 19 09:39:04 sd-100246 postgrey[5229]: Process Backgrounded juin 19 09:39:04 sd-100246 postgrey[5229]: 2019/06/19-09:39:04 postgrey (type Net::Server::Multi...29) juin 19 09:39:04 sd-100246 postgrey[5229]: Binding to UNIX socket file "/var/spool/postfix/postg...et" juin 19 09:39:04 sd-100246 postgrey[5229]: Setting gid to "238 238" juin 19 09:39:04 sd-100246 systemd[1]: Started Postfix Greylisting Service. juin 19 09:39:04 sd-100246 postgrey[5229]: Setting uid to "994" The only problem is that there's no greylisting. I tried to send mails from various mail servers to this machine. Everything gets delivered immediately, and there's no greylisting action in /var/log/maillog. Any suggestions? Niki
Try following the Postgrey guide on the Wiki: https://wiki.centos.org/HowTos/postgrey#head-314ceecc5ece27e0f0a4bf1abcd8ee9356cd1a5e Works for me (allowing for the switch to systemd) _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
