Overview
The node "Mailgroup" provides integration with a mailgroup service, allowing users to interact with mailgroup instances through various operations. Specifically, the "Test SMTP Settings" operation under the "Setting" resource enables users to verify the correctness and connectivity of SMTP configuration settings. This is useful for ensuring that email sending configurations are valid before deploying them in production workflows.
Common scenarios include:
- Validating SMTP server details such as host, port, authentication, and TLS settings.
- Testing email headers and connection parameters to prevent misconfiguration.
- Troubleshooting email delivery issues by confirming SMTP setup.
Example: Before automating email notifications, a user can input their SMTP settings JSON into this node's test operation to confirm that the SMTP server accepts connections and credentials are correct.
Properties
| Name | Meaning |
|---|---|
| Settings (JSON) | The full SMTP configuration object to test. This includes fields like uuid, enabled, host, port, auth_protocol, username, password, email_headers, tls_type, tls_skip_verify, and other SMTP-related options. Users provide these settings as a JSON object to be validated by the node. |
Output
The node outputs a JSON object representing the result of the SMTP settings test. This typically includes success or failure status, error messages if any, and possibly diagnostic information about the SMTP connection attempt.
If the node supports binary data output, it would relate to raw SMTP communication logs or certificates, but based on the provided code and properties, the primary output is JSON-formatted test results.
Dependencies
- Requires an API key credential to authenticate against the mailgroup service.
- Needs network access to the specified SMTP server to perform the test.
- No additional environment variables or external services are explicitly required beyond the mailgroup API credentials and SMTP server accessibility.
Troubleshooting
Common Issues:
- Incorrect SMTP host or port leading to connection failures.
- Authentication errors due to wrong username or password.
- TLS handshake failures if TLS settings do not match the server requirements.
- Timeout errors if the SMTP server is unreachable or slow to respond.
Error Messages:
- Connection refused or timed out: Check network connectivity and SMTP server address/port.
- Authentication failed: Verify username and password.
- TLS errors: Adjust TLS type or skip verification flags according to server capabilities.
Resolving these usually involves verifying the SMTP settings JSON input carefully and ensuring the mailgroup API credentials are valid.
