When you go into Event Notification, checkbox an email address, and click Test email address are you seeing the same thing? On both a test email, and a test problem, I received the emails from the console name and domain specified in
HMC Management,
Network settings,
Including the case of the letters entered in those.

Subject: HMC Electronic Service Agent "from" email address

I've configured customer notifications in "HMC Management"->"Manage Serviceable Event Notification". It works but all messages come from address
ElectronicServiceAgent_localhost@localhost.localdomain. How can i change this address to something like hmc@example.com?
