Hello,
my Centova has stopped sending emails.
i have all the SMTP settings correct, ive even changed the password to make sure its all correct.

but when i press to send a test email i get the below message.  Any help would be much appreciated to help trouble shoot this its been an issue for a few days now and im lost what to do.

E-mail connectivity test
Test result: FAILED - Centova Cast does NOT appear to be able to send E-mails; an error occurred while attempting to send a test message.

Details:
Error sending message from noreply@myemailaddress.co.uk to support@myemailaddress.co.uk
Error: Failed to connect socket: php_network_getaddresses: getaddrinfo failed: Name or service not known
Using SMTP: Yes
Subject: E-mail delivery test

Please refer to the Notification E-mails article section in the Centova Cast knowledge base for assistance with setting up an SMTP server to resolve this problem.

Have you checked that your SMTP server is SSL, and if so - did you include that in the configuration of your SMTP details?
