Hi, if you could help me to resolve my issue here.
when I do following, this enables SPF validation and rejects spoofed emails. However this also starts to reject internal devices and application emails which are connecting to our Exchange server 2013 as Anonymous user.
Set-SenderIdConfig -SpoofedDomainAction Reject
I need to have our internal devices and applications emails working while rejecting spoofed emails from outside.
Its on Exchange Server 2013 environment.
Will appreciate if anyone can help. Thanks.
