Don't know what is going on. I have not exported books to my Kindle or Kindle for PC or my Android phone in awhile. When I tried it stopped working saying my GMX wasn't valid. I checked it was still good but I tried setting up a new account and that one wouldn't work either although both GMX emails were valid and functioning.

I have updated Calibre several times since my last successful export and maybe that has something to do with it but I can't find anything different on the connections to GMX or to Outlook (I tried both ways).

When testing connection:
Traceback (most recent call last):
File "calibre\gui2\wizard\send_email.py", line 223, in test_email_settings
File "calibre\utils\smtp.py", line 181, in sendmail
File "smtplib.py", line 750, in login
File "smtplib.py", line 739, in login
File "smtplib.py", line 662, in auth
smtplib.SMTPAuthenticationError: (535, b'Authentication credentials invalid')

Is this error for GMX?
