BATV ). What do people think?

I guess that BATV can't break CBV, otherwise BATV wouldn't
work for "real" auto-replies not limited to bounce messages.

CBV is SMTP without DATA and MAIL FROM:<>, or isn't it ?  Bye

CBV is
"
MAIL FROM: <>
RCPT TO: isthis(_dot_)emailaddres(_at_)real
QUIT
"

If you reject the RCPT TO: when the MAIL FROM is <> with BATV
then CBV would break so IMHO you have to wait until they try and
do a DATA then you know its not a CBV and then reject it. You
wouldn't reject if the RCPT TO: is a valid BATV encoded BATV message.

Thanks
