Add a boolean flag `authIsActive` to manage redaction of sensitive authentication information in debug logs. When this flag is true, authentication details are replaced with `<auth redacted>`.
Added the `logAuthData` flag to enable conditional logging of SMTP authentication data. Introduced the `SetLogAuthData` method for clients to toggle this flag. Adjusted existing logging logic to respect this new configuration.
Added a new option and methods to enable logging of SMTP authentication data. Updated documentation to indicate caution when using this feature due to potential data protection risks.
Introduced TestClient_SetLogAuthData to verify the proper behavior of the SetLogAuthData method in both client and SMTP tests. This ensures that logAuthData is enabled or disabled as expected, increasing code reliability.

This PR updates the
smtp.Clientto redact any kind of SMTP authentication data when debug logging is enabled. This will be the new default, since we want to offer sane defaults. If the user needs to see the authentication data anyways, two new Client options have been added to enable the logging of auth data:WithLogAuthData()andClient.SetLogAuthData(bool).
