    • The input addresses people (input.to): what it sends cannot be taken back.
    Description, as the server wrote it
    Mail a real paper letter in the Czech Republic via Česká pošta. Provide the letter as a PDF (base64 or URL) or as markdown/text (we render it). Choose ordinary (obycejne) or registered (doporucene). Registered requires a `from` sender address.
