No.. SpamAssassin, by itself, is really just a scanning engine with header modification abilities. It does not do email management, quarantines, etc at all. It receives a message, evaluates it, and modifies it based on the results, nothing more, nothing less. (this is done to make SA flexible.. it's a mail pipe, so you can glue it into almost anything.)
Generally matters like this are handled by integration tools such as MailScanner, amavisd-new, etc, although I do not know of any that provide comprehensive quarantine management. That said, I've never desired such, so I've not looked at length for one. (I mostly just tag mail, and let users filter at the client level as they see fit.)

The clamav plugin for SA is functional, and not difficult to set up, but it's not what I would consider an ideal solution. All it does is cause viruses to show up as a SA rule named CLAMAV. However, Since SpamAssassin can't drop mail directly, you'll still need to get an integration tool to detect that marker in the header and delete the message. > Thanks for any help.
