I'm looking for some general feedback from the community on their experiences with Plesk and SpamAssasin.

- How hard is it to configure?
- Are the definitions updated when the autoupdate process runs?
- Can I configure it on a per mailbox basis?
- If a message is treated as SPAM where does it go? Can the user recover it themselves or does that require an administrator's intervention?
- Can a user create white/black lists?
- Do the white/black lists impact other users on the same server?
- Does Plesk report on the number of mailboxes in a domain where it is configured? For example, if a domain admin adds a mailbox and enables SpamAssasin, do I have visibility as the hoster to bill for that addition?

Thanks.
