@justbob
It’s currently laying on my desk :-(
Couldn’t find a proper way to detect new mail properly yet.

banbutcher

have you a network speed checker running? that could account for the 500mb your using?

blaukon

@banbutcher yes, used screen and nethogs and tried lowering the refresh-rates of some modules and the data-usage dropped quickly

That’s a really great build! Congrats!
I like the (physical) mail notification and pickup idea very much. So please keep us in the loop with how it works out,
