Well, there are still cool stuff that can be done with free tools: At
mine, milter-greylist looks up per-recipient settings in an LDAP 
directory. Settings include whether greylisting is enabled, for what
delays, what DNSRBL to use, blacklist and whitelist. 

Users have access to a web application which enable them to access
and modify their personnel filtering settings. The application also
shows them all milter-greylist activity collected through the stat 
feature: they can see what delivery attempt was accepted, temporary 
rejected, or permanently rejected, and for what reason. 

No filtering is enabled by default. Users that complain about spam are
directed to this tool, and they do use it to perform filtering. As the
only filtering done is what they have configured, there is no room
for lost mail complaints, and there is no administrative overhead.
