Problem Resolution
SMTP Test Failure The cloud service could not connect to port 25 on your connection. Confirm port 25 is open, and also check the text file for traceroute results for that connection, to see where the connectivity error occurs.
Server Security Error

The cloud service could not connect to your domain using the security settings specified in the connection. This may be due to one of the following:

  • the host name could be verified against the certificate. Ensure the common name on the certificate matches the MTA with which the cloud service is communicating.
  • The security settings are set to Encrypt or Encrypt+CN and the certificate is not from a trusted certificate authority (CA).
  • The connection does not support the encryption strength set in the policy (encryption algorithms must support a 128 or 256 bit key).
TLS error The cloud service could not send a message to either the connection or the mail recipient using TLS. If you have enabled mandatory TLS, ensure all security settings between the cloud service, your MTAs, and all required third-party MTAs are configured correctly.
Outbound route connectivity failure The cloud service could not connect to the recipient domain’s MTA. This may be because port 25 is not open, or because the connection attempt timed out.
