Use Exchange Online Protection to block emails from senders with no SPF record
Is it possible to drop or send to Junk any messages where the sender domain either does not have an SPF record, or if they do and it's set to softfail can it also be sent to Junk or dropped?
Hi VisionLarga . No I wasn't able to use this feature as it's not currently available with my 3rd party Mail Security Gateway provider.
So just to be sure i understand you, your mail flow goes something like this, email from the internet > hits your 3rd party filter > then exchange online protection? If this is the case, are you saying you do not see this particular header after it touches EOP? Or are you looking to do this rule from the 3rd party directly.
