Newsletter both TEXT and HTML test email NOT sent: try to change the sender data, remove the return path and the reply to settings.
and also this? SMTP -> ERROR: Failed to connect to server: php_network_getaddresses: getaddrinfo failed: hostname nor servname provided, or not known (0)SMTP connect() failed.
You should contect the provider. Or the server has not the host resolution correctly configured, or there is a firewall blocking the SMTP connections.
Only the provider can solve this problem.
