I had this working at one time but had to rebuild Windows 10 and then everything stopped.
Configureation: Windows 10 Pro, Calibre 5.6, GMX email
I can select a book and send to harddrive and it is there - No problem.
I can select a book and send to email of Kindle, the following happens:

Email successfully sent

Appears to go to the proper email address on my Kindle but never arrives.
It doesn't show on GMX 'Sent' folder but looks like it went through GMX

Same results when I send to my Kindle on Android. Different email address obviously but the same results because it appears to go but doesn't get there.

Any help would be apprecated.
