I have used calibre for years and loved it. I send docs to different kindles using their personal kindle email. However, I updated Calibre to Calibre 3.35 and it doesn't work as it used to. I read the earlier posts and created a GMX account, switching my email to that one now. Unfortunately, it always says unable to send. These are the last few lines in the code. Obviously, I'm doing something wrong. Advice? I have double and triple checked my kindle email, as well.

reply: '535 Authentication credentials invalid\r\n'
reply: retcode (535); Msg: Authentication credentials invalid

Sending failed...
