The point is that not even the admins on ProtonMail can read the content of 
emails, or anything stored on their servers. 

This is unlike Gmail (for example), who also use SSL and TLS, but obviously 
they have some kind of automated way to read the content of our emails and 
know who are all our correspondents. 

And I don't imagine that my Zoho account (or any other) is much better in that 
regard. Zoho is better only in that they do not bother me with useless hoops 
to keep jumping through; whereas in the case of Gmail, I kept getting shut 
out of my own accounts, merely because I sometimes logged in from different

Yeah, there's the rub. *SIGH*

This is super-paranoid, yet also correct. I have various tricks for 
communicating, which do not depend on anything to do with computers or 
networks, but rather use items in the real physical world. (This is just for 
communicating in case of an emergency, when other means are not trusted.) 

I just want to be sure that some of my friends, who live in places that are 
more dangerous than the US, UK or EU, do not suddenly disappear. What may 
seem perfectly innocent here is not necessarily perceived in the same way 
where they live.

Well, at least your email came through here as an encrypted message. But yes, 
it makes no sense to use encryption for the mailing list (except for testing 
purposes, which is what I meant). All our messages here are published online, 
for anybody anywhere to read. 

I have generated my key, but somehow or other Kmail doesn't want to send when 
it is signed and/or encrypted.
