I have same RSS feeds, that I would like to read them via periodicals menu. I can create a .mobi file as need format for periodicals and send it to Kindle PW2 with usb cable or download it from a remote web server, it goes to periodicals menu as I need, but if I send same file it with email to kindle, it goes Docs. So how can I send file to periodicals with email way ?
No, this is impossible.
Since the Kindle email service converts everything to a personal document, you must USB sideload in order to retain the periodical tag.
Calibre can send mails for you. I'd recommend to check the fine documentation:
- And a forum post about handling it: http://www.mobileread.com/forums/showthread.php?t=213166
Update: and I'd recommend to check the source file for the recipe which is not working properly. It might not has the proper setting for the magazine type in it:
publication_type = 'magazine'
Another option to this is using the CLI tools of Calibre with a CLI mail client, e.g. from a shell script (if you are on *nix OS, like:
#!/bin/bash /path/to/ebook-convert /path/to/NEWSPAPER.recipe /path/to/OUTPUT.mobi && \ nail -a /path/to/OUTPUT.mobi -s WHATEVER <<<""
(I'm using this above solution myself.)
