HI,

I made (hacked from acid) this script up some time ago to Install PostGrey & Spamassassin for zPanel on Ubuntu 12.04 - I would assume it will work ok with Sentora looking at the tutorial - anyone interested please feel free to give it a go and let me know.

As will all scripts - please take care and backup!

Code:

#!/bin/sh
#
# Script to install postgrey and spamassassin on Ubuntu ZPanel system, arrogantly hacked from Centos 6.4 and ZPanel 10.1.0 script by acid

#
# Version 1

if which postgrey >/dev/null; then
echo "postgrey already exist"

apt-get -y install postgrey
sed -i '/^smtpd_recipient_restrictions =/ s/$/ check_policy_service inet:127.0.0.1:10023,/' /etc/zpanel/configs/postfix/main.cf

fi

I hope it is of some help.

I've personally just installed this on Ubuntu 14.04 LTS running Sentora 1.0.0 and appears to be working fine! (I didn't use the above script but used the steps provided by Diablo at the top of this thread!)

Thanks for the guide Diablo - Maybe we should look at adding this as part of the main installer

Hi,

How do we check if items on roadmaps are implemented? Is there a flowchart/progress tracker somewhere?
