I disagree - I run a personal mail server and dkim+spf just took a little bit of research to set up, so I&#x27;m very glad this brought them to my attention because I want to do what I can to make my emails trustworthy.<p>If there are any potential downsides to these things I&#x27;m interested to hear them, but it seems like they&#x27;re generally agreed good practices, and hosting your own mail means you&#x27;re signing up for some ongoing learning and maintenance anyway.
