I have reviewed this thread (as well as others) but am unable to resolve my own issue with trying to email to a Kindle (mine and others). Problem is it worked in the past and now no longer is.
I have the Preferences properly set up to send using Gmail and have the correct SMPT and authentication passwords entered. However, I get a "failed" message that Google is receiving an incorrect user/password combination. I tried going to the suggested reading in the error message but the solution is not there.
In a nutshell I cannot even communicate with my own Kindle via email. Here is the log from the "Test Email" option in Sharing:

Logging into Google with the user identity and password works fine. Any ideas?
