How to make the most secure email?

Question

Email

Hello. The customer is interested in how to create the most secure mailbox for free? so that traffic is encrypted and even no services can access official correspondence. I am not well versed in these matters. Do not offer Jabber with pgp, it will be too difficult for all employees to figure it out. Is there anything free and 100% reliable?

Answer 1

PGP should not be ignored, it integrates perfectly into email clients. You just need to choose the most convenient configuration, install it on the machines and conduct training + after some time re-training for those from whom open letters went through your server.

Answer 2

Pigeon mail.
As encryption methods, I can advise you to entrust writing letters to you under dictation.

Answer 3

1) hard encryption on the mail server;
2) transport protocol encryption (SSL);
3) message encryption (PGP)
There is nothing more to add here, it seems.

Answer 4

no, only very paid and very expensive

Answer 5

Never create

Answer 6

Use steganography in spelling errors?
In general, BitMessage

Answer 7

+1 for BitMessage. Installed and working. But two points must be taken into account. First, one click on the link to the left server and your anonymity is over. Cryptography, however, is not. Secondly, the very fact of the exchange of encrypted messages is suspicious. If this is a problem, you can hide encrypted messages in pictures (steganography), but I do not know of ready-made email clients with such a function.
