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
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.
