I don't claim that courier-imap does not scale, in fact, I don't claim anything about courier-imap at all. I simply remark that cyrus-imap has been designed to scale well and this is achieved by using a data base backend. Your comment does not prove me wrong: You seem to indicate that cyrus-imap doesn't scale and refer to a successful install of courier-imap. This doesn't make sense - that logic is flawed. You can only claim that you have found courier-imap scales fine. Well, that's good, then there is choice.
