#3009 new task

Replace postgrey with postscreen

Reported by: strk Owned by: sac@…
Priority: normal Milestone: Sysadmin Contract 2024-III
Component: SysAdmin/Postfix Keywords: spam, spoof, email authentication

Description (last modified by strk)

On #postfix IRC channel they tell me "postscreen" is a newer approach to reduce spam and does the same as "postgrey" plus more:

zilirc | btw don't mix postgrey with postscreen, they sort-of do the same thing 
zilirc | I strongly encourage people to use postscreen because it has more features
lunaphyte | indeed, traditional greylisting software is not really the way to go, these days.  use postscreen

I should add that postscreen is included in the postfix package while postgrey is in a separate package.

Another thing to add: postgrey (greylisting) is making the mail queue grow and slowing down delivery

Until upgrade, the instructions to setup postscreen that apply for us (running 3.4) are here:

See also #2823 which is about upgrading the whole system on the machine running postfix (osgeo6)

Sounds good, it hopefully also stops this rubbish:

The spammer is not subscribed, the list is moderated and still it comes through :(

Markus: list being moderated and mails from non-subscribed still coming through sounds like a bug worth a separate ticket, please file one under the SysAdmin/Mailman category
