    Additional email headers can be specified with the dictionary

    Optionally cc, bcc and attachments can be specified as keyword arguments.
    Attachments must be an iterable and each attachment can be either a
    filename or a file object or a dictionary with filename, content and
    optionally content_type keys.

    If `web.config.smtp_server` is set, it will send the message
    to that SMTP server. Otherwise it will look for
    `/usr/sbin/sendmail`, the typical location for the sendmail-style
    binary. To use sendmail from a different path, set `web.config.sendmail_path`.
