Hi
Over the last couple of weeks we are starting to get reports from different customers that they are receiving alot of NDRs for emails they never sent.
I would like to confirm that this is due to spoofing and nothing else.
If its agreed that it spoofing I would like to confirm that the only tools I have against this problem is a rDNS setup for all the exchange servers and a SPF record.

Hope to hear all your comments on this.
