I use a programm that downloads new articles and pops them in a folder via IMAP. I sign into my email on most devices, be it IMAP, web or ActiveSync, so I can read articles anywhere and my mail server handles syncing read status etc.

Which is a "port" of the very old/established python project with the same name:

If you have a server somewhere, you use cron and configure a list of feeds. Each time a new entry appears you get it sent as an email.
