SquirrelMail

SquirrelMail is a freely-available, open-source webmail program,
which can be uploaded to a server.
It is the only such program that does not have any [privacy-violating]
javascript-dependent essential functions, at least in the anglophone world.
Consequently, it is the program that is most-hated by totalitarian intelligence agencies.

In the early oughties, the south-african free-webmail website webmail.co.za used SquirrelMail,
but, within a few years, South Africa's government bowed to international pressure from
U.S. and british intelligence, by blocking non-south-african IP-addresses
from registering accounts on the site.
Later, South Africa's government again bowed to pressure from U.S. and british intelligence,
by inserting a javascript-dependent parameter into the website's account-registration page,
thus making account-registration non-anonymous.
Later, South Africa's government again bowed to pressure from U.S. and british intelligence,
by replacing the SquirrelMail program entirely, replacing it with thoroughly javascript-dependent filth.

At a later time, in 2015-to-2016, the Squirrelmail-based free-webmail website ruggedinbox.com existed.
The totalitarian fanatics in the U.S. NSA used their "QUANTUM" system
to perma-DDoS that website out of existence.

At a later time, in 2019, the TOR/onion Squirrelmail-based free-webmail website Mail-2-Tor
( mail2tor2zyjdctd.onion/squirrelmail/ ; email-address domain mail2tor.com ) was fully functional,
but then the totalitarian fanatics commandeered that website and mostly-disabled it,
so that it coud only send-and-receive emails with other Mail-2-Tor email-addresses.

Later, in 2020, the TOR/onion Squirrelmail-based free-webmail website SecMail
(Secure Mail; secmailw453j7piv.onion ; email-address domain secmail.pro ) existed,
but then the totalitarian fanatics in the U.S. NSA used their "QUANTUM" system
to perma-DDoS that website out of existence,
along with the javascript-free file-upload website upload.run, in october of 2020,
immediately after both websites were used by a targetted individual
to warn some teenagers about PSSD/PSS.
