    Mailibex is an email library in Elixir : currently implements
    DKIM, SPF, DMARC, MimeMail (using iconv nif for encoding),
    MimeType (and file type detection), a simplified api to modify or create
    mimemail as a keyword list. Next step is a full implementation of
    SMTP client and server, to make it possible to use emails as a routable API for
    events and messages between your applications.
