Neomutt (and probably Mutt too, but I didn't try) seems to be hiding header fields from email, such as the Message-ID field, and fields that are added by SMTP servers when they receive the message....

This isn't exactly what you asked, but the letters-too-small problem could also be solved by using a larger console font. Here is a decent overview of how to change console fonts, though I don't k...
Sorry it was a typo, _ instead of -, that caused the problem. I want to have a key combination to alter the keymaps. It worked with one for us and one for hu, but now I want to use one key combina...

I was told that an IPv6 link-local address — typically starting with fe80:: — is derived from the interface's MAC address. Here are some instruction on how to do the conversion. But the conversion...
Restarting NetworkManager should be enough: sudo systemctl restart NetworkManger
