Tried again, but it doesn't appear to have worked. I got this message:
These recipients of your message have been processed by the mail server:*****************; Failed; 5.1.1 (bad destination mailbox address)
Remote MTA smtp-in.orange.fr: SMTP diagnostic: 550 5.1.1 Adresse d au moins un destinataire invalide. Invalid recipient. OFR_416 [416]
(* I deleted your Email address).
Are you OK?
