Quarantine Management

[Dennis B. Hopp]

What are people using for quarantine management with spamassassin?   
I've been using maia mailguard and it works decently but hasn't been  
updated in what seems like forever (svn has been updated, but no  
formal release).

Just wondering what other tools are out there that people like.
I use postfix as my MTA right now, but am not completely opposed to  
using something else if necessary to use a specific quarantine system.

Thanks,
