I've seen the announcement that version 6 is now in beta and includes per user white/black lists. I've got a couple questions about this feature:
Will users be able to maintain the lists through ZCO? Or will they have to put all updates through the webmail interface?
How many addresses can they put on the lists? If there is a limit, is it per list? For example say the limit is 50. Is that 50 total or 50 whitelisted and 50 blacklisted?
