Single point of failure: what happens to the mail when the database goes down? If you have one database server for this type of thing, you may as well have a single MX host. I've been contemplating implementing greylisting via a replicated database, so that all four of my mail servers can have access to the same dataset, and it wouldn't matter which of them a sending host connected to, including retries. I haven't got the implementation yet (if anyone knows that this has already been done, pointers would be welcome), but in my setup, I don't think I can use anything like greylisting otherwise (and I haven't been able to use Bayes, for example). -- ---------------------------------------------------------------------- Sylvain Robitaille [EMAIL PROTECTED] Systems analyst / Postmaster Concordia University Instructional & Information Technology Montreal, Quebec, Canada ----------------------------------------------------------------------
