The directions I gave are what should work.

 I had already tried that but I went ahead and tried it again.  It 
did not work for me.
Auto converting the AZW3 file to MOBI on auto-add, then manually converting the MOBI to EPUB, then emailing that EPUB to my Kindle works consistently.
So I'm still looking for a solution to get Calibre to use the MOBI file when it auto converts to EPUB on emailing.
