The Nice Man Said: You've Got Mail!
This server is a mail host. This host aims to be secure and compliant to modern standards. And independence from larger mail providers.
This host is not owned by a mail provider! Please do not get in touch with us asking for mail services. This is a private, secure mail server coming from somebody who believes that security – and your personal data – is best in your own hands. If we do not know you, your aunt, your dog, or your dog's aunt, we have nothing to offer to you.
P.S.: If you don't see an envelope above the header but just some garbage: fetch a modern browser. This is unicode and post-2010, you may want to update.
