This health check ensures the test email is sent only once to prevent
|
|
hitting SMTP rate limits due to multiple health check executions.
|
|
The logic checks for a temporary file (/tmp/email_sent) to determine
|
|
if the email has already been sent. If the file exists, the email
|
|
is skipped, but the health check continues by verifying the HTTP service.
