Welcome to Nick's Random Musings

If you are using the newer snap plugin for letsencrypt, you may need to add you subdomains like:

certbot --expand -d gully.org -d www.gully.org

Recently I've had a big increase in spam from gmail itself, so I wanted to whitelist only the people I want to hear from gmail.

All the people who mail me

grep "^From:" /var/mail/nick >> whoknocks.txt

All the people who mail me using gmail

grep "\@gmail.com" whoknocks.txt >> just_gmail.txt
