I had $wgSMTP set up to talk to a remote exchange server, but password resets just weren’t working from the wiki. It turns out all I was missing was the ‘php-pear-Mail package’ (in fedora, for debian or other systems it may be a different package name). I started by checking any logs related to this problem… mail.php missing in UserMailer.php - dependency problem

I read in a bunch of places that you can’t use HTTP["scheme"] to redirect http:80 traffic to https:443 without using 2-3 levels of nesting with socket and host. But that’s just not true. The only reason it doesn’t work at first is because http is a subset of https, so be more specific with http$ and it works with just one line in lighttpd.conf.
