A-D site not responsive using your own photographer link.

[Doug Robertson]

I average about one request per week by email for photo usage by a sender who has contacted me by email using your link-Contact Photographer. Occasionally those email requests are flagged as suspicious as "Not being from the sender address, etc". That happened to me today. And, the request was judged suspicious by me because of the photo linked and the specifics of the request.

You have a link to Report Suspicious Requests, which I did using your link.

Yet, I got a message: Delivery to the following recipient failed permanently:
error@airport-data.com

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain airport-data.com by mail.cqww.net [198.50.204.192]

The error that the other server returned was:
550 5.1.1 <error@airport-data.com>:Recipient address rejected. User unknown in virtual mailbox table

My other incoming and outgoing emails today show no problems.

Please explain and correct your apparent communication problem.
