Stressed? Are you serious? Have you measured an actual problem, or are you inventing one that you think exists?

You could try using the "spamtrap" feature of the bofh file (see man courier(8)). I'm mostly sure that's checked before user lookups. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
