Hello, I've been using GMX to send to Kindle for many months now, but starting in beginning of November Amazon has been rejecting the emails.
Test emails go out fine, but I noticed when sending to my Gmail account the email would go to the Spam folder.
I've set up the GMX credentials in Calibre just like the FAQ says through the "Use GMX" button. But in the header information I can't tell if it's sending via mail relay or not?
Here's the message I receive in my GMX inbox:
Code:

A message that you sent could not be delivered to one or more of

The following address failed:
