Exchange can https://markgossa.blogspot.com/2016/01/block-spoofed-email-exchange-2010-2013-2016-part1.html, but I had loads of NDRs.
It turns out that installing the SenderID Agent also installs the other spam agents and that the NDRs where a result of Content filtering Enabled with default SCL rating Reject, I have disabled Content Filtering and again enabled SenderID Filter.
I have Hardfails sofar for lazy domain admins that forgot to include their mailing list provider and have set themselves a -all hardfail for not listed.
Thanks,
Fred
