Per User Anti-spam Quarantine Reporting/Management

[Tanstaafl <tanstaafl@libertytrek.org>]

    Ok, a question about anti-spam software...
    
    My new server will be a multi-domain MX gateway/anti-spam system
    running postfix with postscreen enabled, and
    Amavisd-New+SpamAssassin (unless someone has a better suggestion).
    
    Since it has been a looong time - are there any better options for
    an anti-spam solution than just amavisd-new+spamassassin?
    
    I'm specifically interested in adding some kind of per user
    anti-spam quarantine+management+reporting capabilities (as opposed
    to just tag+deliver), if possible.
    
    Searching online reveals Maia Mailguard, but it seems to be not well
    maintained - most importantly, it apparently doesn't work with
    modern versions of PHP.
    
    Also, I saw a reference to something called 'SAQ', a 'SpamAssassin
    Quarantine system', but it seems to have gone bye bye.
    
    One option is ASSP, which I experimented with a very, very long time
    ago, but I never implemented it because I really, really don't want
    one big perl script as my primary front line gateway defense.
    
    I may see if I can set up ASSP to just be an after the fact spam
    filter rather than the gateway, if the per user Reporting/Quarantine
    management will still work properly.
    
    Thanks for any suggestions anyone might have...
