I answered him back, but my message was rejected by his email server:
Address not found Your message wasn't delivered to ...@optonline.net because the address couldn't be found, or is unable to receive mail. The response from the remote server was: 550 5.1.1 Invalid recipient ...@optonline.net
I wrote to firstname.lastname@example.org to notify this problem, but the message bounced back as well. As I don’t know how to get in touch with Mr. Joseph Corona otherwise, I hope he will read this communication and write me again using a different email address. I would be glad to help him to get the medal for his father.
