Unable to send messages
SolvedHello,
I can no longer send my messages regardless of the recipient. The error message is:
The message sending failed.
An error occurred while sending the email. The mail server responded: <unknown[2a01:e0a:51d:74f0:dd43:a489:bc54:f7e6]:50193>: Client host rejected: Access denied. Please check the recipient address ***@*** and try again.
Thank you in advance for your help
best regards
