if I have to check email on an untrusted shared machine, I can redirect it to a low value gmail account with low value password and read it from there. It still is not a perfect system, e.g. because some of the emails that can end up accessible from there may be too high value for the situation, but, well, it’s better than nothing.
Now, if I want to respond to emails so received or in general send emails from my high value account (or, “as if” from it) it seems that I am SOL. So for the time being I am forced to use the low value one for this purpose, which inter alia may mean gradual creep of it towards the high value, primary email category. And generally I think it’s a bad thing all around.
Anybody knows an existing solution to the dilemma? Or is this a potential market niche screaming for a good hard implementation?
