Hi all,
thanks for yours answers
first, yes you are right, we should refuse mails from domains with no
A/MX records, we are going to fix it.
secondly, in my mail, please read anti-virus and no anti-spam. I
mistyped, of course anti-spams do not send back mails, but anti-virus do.
Yes we have suppress SPF record after our tests.
That record said that the only authorized host for grenoble.cnrs.fr is
147.173.1.26 (labs.grenoble.cnrs.fr).
We have sent a mail from reflector.grenoble.cnrs.fr (147.173.3.39)
simulating a mail from user(_at_)another(_dot_)existing(_dot_)domain(_dot_) My question was
why SPF does not base its analyses on that IP address ? (presuming that
address is more reliable that the domain announciated in FROM field, no?)
thanks,
daniel
