Proton Mail Bridge
Proton Mail Bridge application
Proton Mail Bridge is a desktop application that runs in the background on Windows, macOS, and Linux to enable users to access their Proton Mail encrypted email accounts with traditional email clients like Outlook, Thunderbird, Apple Mail, and others via local IMAP/SMTP servers. Because standard IMAP cannot natively decrypt end-to-end encrypted messages, Bridge acts as a translator that downloads encrypted mail, decrypts it locally, and serves it to your preferred mail client over a local server, while encrypting outgoing messages before they’re sent to Proton’s servers. It provides a seamless integration layer for users who need offline support, familiar local client workflows, or tighter integration with desktop tools while preserving Proton’s zero-access encryption model. ... -

Sanspam
Interactive spam removal utility
...Sanspam is inspired by Save My Modem by Enrico Tasso and SpamX by Emmanual Vasilakis, which are two simple, easy to set up tools that I used to use, but aren't maintained any more and require too much work to justify update. Sanspam supports POP and IMAP accounts, and also supports SSL for secure connections. This is more suited to those who use e-mail clients and prefer to download messages to their computer, but also prefer not to allow spam, or potentially harmful messages to be downloaded at all. Instead of running a risk having it downloaded by the e-mail client, Sanspam allows you to delete it on the server, without being exposed to any attachments or e-mail content. -
