The address does not exist, or is no longer active, at this provider. Remove it from your list and check for a typo in the local part or the domain.

The sending IP or domain is on a blocklist the receiver checks, so mail stays refused until the listing clears. Find which list flagged you, fix the underlying cause, then request removal. Delivery can stay blocked for up to a day after delisting while caches refresh.
