Email notifications and Share link URL designations

AEM 6.3.  Mail is configured and i do get notifications now from asset workflows.  All references to links have base URL as localhost:4502 in the notifications.  Such as:

Content: http://localhost:4502/content/dam/aem-docs/VID_digital-hub-DAM-overview_EN.mp4/jcr:content/renditions/original

  -------------------------------------------------------------------------------------

View the overview in your http://localhost:4502/aem/inbox

And when an asset is selected and one want to utilize the "Share  Link" function from the Nav bar, it also is using localhost as default base URL.  How can these be share to reflect the appropriate DNS addresses?
