First, thank you.
Second, the question I want to do is similar to the following:
Question: How do you specify the osgi config of a java class in Publish Run Mode?
Answer: (Node Location) /apps/system/config/org.apache.felix.webconsole.internal.servlet.OsgiManager jcr: primary type = sling: osgiConfig
Third, reformulating the question:
How do you specify the email config of a java class in Pusblish run mode, in aem?

Thank a lot.
