Your sample message path is correct.

I get an email from b-j82n1mgrxfpxv@rts.kijiji.ca that has DMARK set so as to prevent auto forwarding.

Currently it is blocked from being forwarded via auto forwarding to another outlook account, but I can manually forward the message onward.

Is there a way to incorporate your service to forward the message that the original sender is trying to prevent forwarding on, to my main email address?
