I thought the exim spec link provided was pretty clear: Bounce address tag validation (BATV) is a scheme whereby the envelope senders of outgoing messages have a cryptographic, timestamped tag added to them. Genuine incoming bounce messages should therefore always be addressed to recipients that have a valid tag. This scheme is a way of detecting unwanted bounce messages caused by sender address forgeries (often called collateral spam), because the recipients of such messages do not include valid tags. -- -------------------------------------------------------- Dave Lugo [email protected] LC Unit #260 TINLC Have you hugged your firewall today?
