I got Calibre up and successfully running. Converted a couple of my epub books to azw3 (I hope that's good for my 9th gen Oasis - just guessing). I tried using my usual gmail, but I got the same type of message, did a search, found people have all sorts of problems using gmail for STK, so I took the calibre direction and opened a GMX email and followed the tabs in calibre.

Here is the message when I do the "test":

Traceback (most recent call last):
File "calibre/gui2/wizard/send_email.py", line 236, in test_email_settings
File "calibre/utils/smtp.py", line 187, 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')

I have done a search and am trying to learn and make sense, but do not understand any of this yet. It does seem to be a common with sending documents through email, and not a calibre thing. I hope it's something simple and someone can help me with this.
