[Kolab-devel] Kolab server - greylisting (long)

[Andreas Micklei]

I have also installed postgrey and integrated it with kolab with a much 
simpler although not as clean approach:

- install postgrey as delivered for your Linux distribution (yum install 
postgrey on CentOS)
- configure postgrey to listen on a TCP Port (for example 60000, 
put 'OPTIONS="$OPTIONS --inet=60000"' into /etc/sysconfig/postgrey on CentOS)
- put a check policy line with the correct port number into your kolab postfix 
main.cf ('check_policy_service inet:127.0.0.1:60000')
- enable postgrey startup during system startup ('chkconfig postgrey on' on 
CentOS)

In general just follow the instructions of your Linux distribution or general 
instructions to set up postgrey. Just put the check_policy_service line into 
the kolab postif main.cf instead of the one that comes with your 
distribution.
