0017771: app-greylisting whitelist is massively out of date
Migrated from: https://tracker.clearos.com/view.php?id=17771
Reported by: NHowitt
In both 6.x and 7.x the whitelist file /etc/postfix/postgrey_whitelist_clients provided with the app-greylisting dates back to 2011. There is an updated version available at http://postgrey.schweikert.ch/pub/postgrey_whitelist_clients. [^] A cron job is needed to regularly (monthly) update this file and restart postgrey.
Very importantly, the newer file whitelists Microsoft Exchange Online (Office 365) and possibly amazonas as well as others
This app is touted as being very important for fighting spam, but the out of date whitelist causes issues.
I have a cron.monthly 7.x cron job: wget -q -N http://postgrey.schweikert.ch/pub/postgrey_whitelist_clients [^] -O /etc/postfix/postgrey_whitelist_clients /bin/systemctl condrestart postgrey.service
This does the trick but could be tarted up the ClearOS way.
Note the same comment applies to 6.x
PBaldwin: This requires an updated SDN engine. Wait for 7.6.0. DLoper: SDN engine updates are getting delayed. Pushing. (to 7.6 Updates)
