Are you sending them .azw3 files, or .mobi? I have heard people successfully send them .mobi, but not that they successfully send .azw3

Kindlegen accepts three different types of input:

HTML
OPF (manifest containing references to all elements of the book)
EPUB (yeah, that kind )

So you could just convert the EPUB using Kindlegen instead of calibre.

The advantage is that it will contain dual MOBI/KF8 content, which gives a MOBI fallback for older devices but still lets new devices see AZW3.
