One reason why I mocked the absurdity of 'needing' a decrypted ethernet system to access the files of your rPi, 2 meters away [PC rPi] is the annoyance from the fact that my 90's perfect email system has been "upgraded" to a frustrating gmail facility.
In my 3rd [going 4th] world location, the new/remaining ISPs can only operate like CocaCola/KFC franchises: being managed by US corporations.
So, I accept that I'm forced to use gmail with ssh, TLS ..blabla. Documentation on setting up the SSH for gmail via pop, refers to use of `fetchmail`. I don't want to get married to fetchmail, and would prefer to confirm with rPi's email facilities.
BTW: rPi + keybrd + old-RCA:B/W monitor + 3g-dongle; works fantastically. And setting a bigger than default FONT is OK for 3rd-world PAL-TV displays.
How do you handle your email by rPi, via ppp with a 3G-dongle, without ethernet?
==TIA.
