Configure "greylisting" in UCS 3.2

I have a UCS 3.2 server with Zarafa configured for email. I am interested in setting up mail “greylisting”. I have found the following script via google:- … &peg=11319

Is it just a simple case of running the script on my UCS or is there more to it than that? Apologies if the question seems a little naf, but I am neither an experienced mail admin or skilled scripting person.


this script is part of the package “univention-postgrey”. You can deploy it with

univention-install univention-postgrey

or by using the UMC.

Once the package is installed you will find a set of UCR-variables to tune the behaviour of postgrey.

ucr search greylisting

Thanks you so much Dirk. I am new to UCS & was until now unaware that additional packages are available through the Extended Software Management tab in the App Centre.
