Greylisting - postgrey

[David Southwell]

Hi

I wonder if someone could be kind enough to post examples of the entries 
required in relevant configuration files to implement postgrey on mailserver 
having a number of virtual mail hosts and for which it also supports mailman 
for a number of virtual apache hosts.

Please bear in mind I am very new to postfix, mailman  & postgrey <chuckles>

thanks in advance
david
