Truster Sender not working?
Question asked by Daniel McFalls - 2/18/2020 at 12:38 PM
A user complained that a designated Trusted Sender is still being treated as a SPAMMER.  Meaning that the SPAM score from the Trusted Sender's message rated high enough (barely) to be moved to junk.  The kicker was no DKIM record.  See the header below.

I thought that a Trusted Sender was just that.  The Trusted User could send you anything short of a virus and the message would pass.  Please explain the use of Trusted Sender.

the headers you pasted shows that DKIM is failing for this e-mail
Trusted sender is not effective when the reason for failing is SPF or DKIM failure and as far as I know there is no way to disable this. 
You should inform the sender that he's having a DKIM issue as it probably also cause him delivery issues to other recipients.

Apparently there is nobody from SmarterMail monitoring these forums.  Thanks for saving me $800 renewal fee.

Hello Daniel, and sorry for the delay on this. We do monitor our community but are not able to get to all posts on a regular basis. With that being said, Trusted Sender emails will still be subjected to basic spam checks (such as SPF/RDNS) to confirm the trusted message is not being spoofed by a malicious party. This cannot be disabled, and prevents outside agents delivering spam and dangerous content to your users behind the label of Trusted Sender. Hope that helps.
