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)

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
