I finally got around to fixing the contact form that’s been broken for about a year. When I moved hosts I never got around to setting up a mail server so that my server could send outgoing emails. I finally got Postfix installed and configured, however while attempting to get email to work on the server I realized that PHP was horribly misconfigured, and that I was using an obsolete version of Ubuntu that had reached its end-of-life phase. So, after doing a dist upgrade and reinstalling PHP7, I’m back up and running; hopefully nothing is horribly broken now.
