remote-mail protocol now in use on the Internet: POP2, POP3, RPOP, APOP,
KPOP, all flavors of IMAP, ETRN, and ODMR.  It can even support IPv6
and IPSEC.

Fetchmail retrieves mail from remote mail servers and forwards it via SMTP,
so it can then be read by normal mail user agents such as mutt, elm
or BSD Mail.  It allows all your system MTA's filtering, forwarding, and
aliasing facilities to work just as they would on normal mail.")

Dovecot encryption plugin.  This plugin adds individually encrypted mail
storage to the Dovecot IMAP server.  It is inspired by Posteo's scrambler
which uses OpenSSL and RSA keypairs.  TREES works in a similar way, but uses
the Sodium crypto library (based on NaCL).

How it works:
@enumerate
@item On IMAP log in, the user's cleartext password is passed to the plugin.
@item The plugin creates an argon2 digest from the password.
@item This password digest is used as a symmetric secret to decrypt a libsodium secretbox.
@item Inside the secretbox is stored a Curve25519 private key.
@item The Curve25519 private key is used to decrypt each individual message,
using lidsodium sealed boxes.
@item New mail is encrypted as it arrives using the Curve25519 public key.
@end enumerate\n")
