mail without password and secure

[toujour]

Hi,

 is there an old script that works otday for send an email to an STMP without password and secure ?

function mail(to, subject, message)
  -- make sure these settings are correct
    local settings = {
    -- "from" field, only e-mail must be specified here
    from = 'MAIL@SEND.COM',
    -- smtp username
    user = ' MAIL@SEND.COM ',
    -- smtp password
    password = nil,   -- NO PASSWORD
    -- smtp server
    server = 'IP_SMTP',
    -- smtp server port
    port = 25,
    -- enable ssl, NO SECURE
    --secure = nil,
  }
