I have a firefox relay address for forwarding to my hotmail address. Several emails that I have been assured were sent have not been delivered to hotmail, neither to the inbox nor to junk mail (some may have pdf attachments). Is there any way I can see what firefox is filtering out (perhaps wrongly identifying as junk). The missing mail is not appearing in junk mail on hotmail.

I have logged into the relay email but here seems to be no way of getting to the inbox of the relay email nor the junk box of the relay email
