What mail clients for Linux work without saving mail from the user?

Question

linux

It is necessary that all mail saving takes place on the mail server, and only the settings of the program itself, as well as server addresses, logins and passwords for mailboxes are saved in the program, but this is optional.
That is, you need a program that replaces the web interface on mail sites.
Perhaps I asked something obvious, I don’t know exactly how email clients work.

Answer 1

Any with IMAP

Answer 2

There are two mailbox access protocols: POP3 and IMAP.
POP3 - mail is downloaded from the server and stored locally on the client.
IMAP - mail is always stored on the server, headers and a readable letter are downloaded to the client.

Answer 3

Email clients are designed the same way as web clients, only they save local data (in a database or in email files).
To not save - find and check the "Do not save" box.
