That's possibly true, but look at this. A greylisted message: mimedefang[17175]: p0I4xvRE017628: Filter time is 85ms A scanned message: mimedefang[17175]: p0I50ACP017683: Filter time is 906ms On a busy system, this can make a huge difference. SpamAssassin scanning is by no means cheap. Regards, David.
