Hello,
I noticed that I have a file "/var/mail/username" on my computer. Some programs put messages in it. I would like to read those messages in Gnus. What backend should I choose to do this? I don't want to install any servers on my computer, I'm trying to keep my Debian installation minimal. It would be best if Gnus could simply read this file without connecting to localhost. Is this possible? Or maybe I should start learning to write my own backends for Gnus?
