I have also had the same problem with my Kindle Touch. I e-mailed Amazon as follows; maybe others would like to base their e-mail off of mine? Send it to firstname.lastname@example.org
I would very much like to have Calibre or KindleFeeder News Feeds e-mailed to my @kindle.com address work as fully-functional .pobi files, so that I can use the "Sections & Articles" navigation page on my Kindle Touch. Can you enable this?
It looks like others are having the same issue, and discussing it at https://www.mobileread.com/forums/sho...d.php?t=157664
Any idea when this might happen? Thanks very much.
