Hello! You've most likely stumbled upon this domain because I've signed up for your service or mailing list using an e-mail address with this domain in it.
The various inboxes under this domain are used for bucketing all the kinds of mail I receive, as well as to limit exposure to and aid research of data breaches.
My email is hosted at Fastmail [referral link]. I'd love to do it myself, but unfortunately, as much as most people would like to make it out to be, self-hosting mail is actually kind of difficult, and Fastmail is the provider in the sweet spot of being large enough to fail and to get through most spam filters while also being highly privacy-conscious and actually profiting from the users paying them.
At times I've considered setting up a different service to accept incoming communication, but thus far there has been less than zero demand, so I suppose email is fine. If you feel like contacting me, feel free to email any address at any of my domains; it should all reach me in due course. I'm also available on Signal and am happy to provide details to continue the conversation over there. (I used to be a proponent of XMPP, but seems like its usability story has turned out to be quite poor.)
