Hi, I would like to know the performance of a cyrus imap/pop3 server. I've got 20000 users writing about 2 mails/day, whereby one mail has approx. 100KB. What will be, in your opinion, the estimated memory- and cpu usage per user, when 100 of them send their mails at the same time? (Is there a document which tells me what cyrus 'costs'?) Thanks. Mike
