I think the point is in rejecting most of these email as soon as possible. For this to work, the front-end SMTP server has to know your users. If it doesn't, you accept these mails for further processing - spam & virus filtering, which are CPU consuming and just after it your server realizes that there is no recipient for it. For the same reason I have some regexp patterns build into postfix body_checks for most common viruses. Postfix rejects these mails immediately. This usually catch about 90% of viruses, so I save a lot of CPU in virus checking of incoming mail... -- bYE, Marki ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
