I'm finally wrapping up a little webdav tool that's been on my todo list for years. It's just a simple tool to copy directories over webdav. I tried using Cadaver but I kept running into strange errors with it. And this one ties in with an unusual authentication setup. Might open source it, haven't decided yet.
Also dicking around with DMARC tools. Was unhappy with all the existing tools, want something simple I can run semi-locally for a bunch of low volume email domains. Haven't decided yet how that will turn out, still in the reading specs & tinkering stage.
