I used the error@airport-data.com link at the foot of a redirected email, to report a possible scam, but my email server rejected the address:
The mail system
<error@airport-data.com>: host mail.cqww.net said: 550 5.1.1
<error@airport-data.com>: Recipient address rejected: User unknown in
virtual mailbox table (in reply to RCPT TO command)
