Is there anything wrong on Orange.fr and wanadoo.fr domains lately ? Our client's recipients went to Hard Bounces. I actually don't understand why suddenly their email become invalid, people that are actually quite active. Opening and clicking on the NL.

Could it be closing themselves ?

The errors you quote translate to "user unknown". Perhaps the recipients closed their accounts? Or stopped paying their bills and their mailboxes were shut down?

Continuing to send mail to mailboxes that bounce hard is unlikely to do your reputation much good!
