I must be missing something here. In order to scan an email you must receive the email (I don't mean accept). How can rejecting/accepting emails at this stage make any significant difference in bandwith used (let alone a quadrupling of bandwidth)? > I only > have 1TB a month.

How much mail do you handle that can make an impact on such a huge bandwidth allowance? Are you running an ISP? ;-) I have 64GB/month for each of my two (virtual under Xen) servers and I've never had to think about bandwidth used by mail even when I was hosting several domains for friends/family. -- David Hart <[EMAIL PROTECTED]> -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
