Bounce
Address Tag Validation (BATV)
Clearswift Gateway can use Bounce
Address Tag Validation () to eliminate email bounce attacks (back-scatter)
where the spammer forges the email address to be that of a legitimate
sender causing the legitimate email address to receive any bounce messages
for that spam.
Using BATV, the Gateway can determine
whether the original message originated in the company mail domain. For
more details, see http://mipassoc.org/batv/draft-levine-batv-03.html.
For more information, see Configuring BATV.
