Sequence problem - Delivery has failed

I am having a problem with a sequence - I already used in past sequences without any problem , what changed now?

Delivery has failed to these recipients or groups:

example@xxxx.com ognized as a valid sender. The most common reason for this error is that the email address is, or was, suspected of sending spam. Contact the organization's email admin for help and give them this error message.

Diagnostic information for administrators:

Did this happen more than one time? It seems to be related more to the receiver than to the sender...

Happened with 450 emails I sent a few hours ago. All of them had the same error and message.

All of the emails I sent were to people who I am in contact with, they are not spam at all.
