Pine was probably the first UNIX application I used back when I was at school. Decades later I decided to give it another go and it’s still good. It’s certainly memory friendly and it gets the basic job done.
The only problem is the binary package does not support password saving. Well I guess if the application need to pass on credentials to remote servers, password needs to be saved and even with encryption, it needs to be decrypted at some point. Maybe I can use kerberos?
