[JimReid]

I have had great luck with Calibre and in the past updated everytime they say there is a new version. I have converted all my books to MOBI and in the past they transfered to my Kindle (JIMREID_698@kindlecom) and to my android phone (jimreid45_3e0666@kindle.com) with out a problem. One of the updates must have changed something because they will not transfer any longer.

Spoiler:

Looking at the transaction process:Starting job: Email Hush-Hush to JIMREID_698@kindle.com

Email successfully sent

Everything looks successful, except the book doesn't get to the device. When I save to a drive it works fine but the email transfer stopped working. I have checked all the spelling and cases of the receiving devices and everything seems in order.

Any ideas would help.
