export connections

[JimReid]

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?

You did not say how long 'awhile' is

Preferences:sharing books by email:
have you verified the settings are STILL GOOD (what did the test email button return ?? )

IIRC GMX did some changes quite awhile back

(I use my ISP, so I am not a good Google helper)

The error is rather clear. The credentials you are attempting to use to connect to GMX have an incorrect username, an incorrect password, both are wrong or your connection setup is hooped.

To quote from one ISP's web site:

Error: SMTP Error 535
What's Causing This Error

SMTP error 535 indicates an issue with the client's authentication with the email server. It may be the result of many issues, some of the most common causes being:

Invalid credentials.
Disabled account.

Invalid or incompatible Authentication Methods.

Solution - Here's How To Resolve It

Depending on the cause of this error, the user may need to take different approaches when attempting to fix this error.

The user must validate the credentials used to login into the email server.
Check if the account is in working order and is not disabled.
Validate the SMTP configuration to check if the connection encryption and authentication settings are compatible with the email server.
