A neat trick I learned from someone here on nostr that I finally got to setting up today. On my postfix mail server I have a wild card that forwards any emails to any user in my domain to my main user account. Then when I need a burner email, such as a gym membership or something, on the spot I just make up an email address and hand it over. When the spam starts rolling in I just hit a key in neomutt that adds that burner address to a shit list and all emails to that address get sent to /dev/null and bounce. Bloody beautiful.
