Default timeout for healthcheck by kubernetes is too low. As we wait up for 2 seconds for the Postfix and DKIM to respond, this exceeds the threshold and the healthcheck fails with: ``` Readiness probe failed: command "sh -c /scripts/healthcheck.sh" timed out ``` By simply increasing `timeoutSeconds` this issue is resolved.
