Is it possible to enable SPF filtering for spoofed emails in Puremessage for Exchange 18.104.22.168?
Thanks in advance,
PureMessage for Exchange cannot do SPF filtering. Central Email Gateway, PureMessage for UNIX, Email Appliance, and XG/UTM Firewall would be the products that can perform SPF filtering.
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.
