Safenote is the free, fast, and secure way to share files and notes with end-to-end encryption and a link that expires automatically. And also it's a free cloud-based service that is functioning via an encrypted SSL tunnel. Safenote doesn't require you to create an account before start using the service and no password or email required. This free service enables you to send a self-destructing message or file to someone. This means once they view the message or download the file, they will no longer be able to access it again after the view count has reached zero. This ensures your message is read by no one but the reader and all evidence of the message is erased. Messages are also anonymous unless you add any identifiable information to your message. If you share your passwords or private, sensitive data via email or chat, copies of that data are stored in a number of locations. If you use Safenote instead, the data stays for a single viewing, which ensures that someone else can't read it later. It allows you to send sensitive information in a secure manner, ensuring that only one person can see it.

I have tried several, and liked none of them. I'm currently on Geary, but it's lacking in functionality, and it has things like search results being a bit different upon each of my searches. Starred messages cannot be shown on top. Eyeroll. I think Evolution and Thunderbird are the top contenders, and of the self-hosted ones, Roundcube. https://wiki.gnome.org/Apps/Geary https://roundcube.net/. - Source: Hacker News / 3 months ago
You could try a standalone email client like Mozilla's Thunderbird, or if you're experienced running a web server, you could check out something like Roundcube. I suppose you could even run it locally if you're familiar with PHP and/or Docker. Source: about 1 year ago
What I really miss is a "web companion" for Thunderbird, basically something like https://roundcube.net/ or https://www.horde.org/apps/webmail, but a bit more powerful and with better UX. I'd like to use a Google Addressbook within such app, for example (there is a completely outdated plug-in for RoundCube). Another important thing would be powerful and fast search. - Source: Hacker News / over 1 year ago
Alternatively if you want to keep what you have I wouldn't recommend using the SoGO even though it's the nicest and most modern option. Mainly because it's a full groupware client and will require a lot of configuration. Instead using Roundcube is probably your best option. Source: over 1 year ago

Other settings are optional and therefore, not important for this purpose. Click create message. Then share link to opponent. (Do not give password yet) The other player waits until this step is completed. Source: over 2 years ago
