I'm guessing you guys that are actively working with your controllers may know this already. I don't mess with my controller much these days since I have it setup. But after having a minor incident this weekend, I realized I did not get the email alert from the controller. Apparently at the beginning of October, the gmx mail service, the one that Neptune essentially endorses, stopped working with the controllers causing emails to fail.
Neptune was able to make this work again with a firmware update. So, if you have not updated your firmware in a few months, you'll need to do that if you are using gmx as your smtp mail server. The new firmware 4.30 also apparently gets you setup for Fusion the new cloud based interface.
