Hello people,
each time I send a book via Calibre using @gmx.com mail, Amazon asks me to verify the file.
I tried to change my kindle mail from
myname@kindle.com to
RandomLettersAndNumbers@kindle.com and still it asks for confirmation.
I tried to create another account on gmx.com, and results are still the same.
Obviously, all the mail addresses I use are on Amazon's WhiteList.
How can I solve this?
I have a Kindle Paperwhite [10th generation] with FW 5.13.4 and I use Calibre 5.9
