email?

[Fred]

I am using the standard script to send email. LM5 v20191015.

No matter what host I set in server, I get an error about "string: 535-5.7.8 Username and Password not accepted. Learn more at
535 5.7.8  https://support.google.com/mail/?p=BadCredentials c5sm15367699wrs.73 - gsmtp"

Why on earth would GOOGLE be there if I ask it to go to "sss" ???

How can I debug this?
I have tried all the combination of 'secure' found on the forum in various posts over the years; this is really confusing but in any case does not change anything since GOOGLE is always back as error.

Thanks for any help or pointers

Hi,

Couple of things to check:

1) Make sure DNS and DG are set correct in the interface settings (otherwise you have no internet access)
2) Enable https://myaccount.google.com/lesssecureapps on your gmail account (otherwise mail from machines is blocked by google)
3) Use these settings in the common functions:

Code:

-- send an e-mail
function mail(to, subject, message)
  -- make sure these settings are correct
  local settings = {
    -- "from" field, only e-mail must be specified here
    from = 'yourmail@gmail.com',
    -- smtp username
    user = 'yourmail@gmail.com',
    -- smtp password
    password = 'yoursecretpassword',
    -- smtp server
    server = 'smtp.gmail.com',
    -- smtp server port
    port = 465,
    -- enable tls, required for gmail smtp
    secure = 'tlsv1_2',
  }

  local smtp = require('socket.smtp')

  if type(to) ~= 'table' then
    to = { to }
  end

  for index, email in ipairs(to) do
    to[ index ] = '<' .. tostring(email) .. '>'
  end

  -- fixup from field
  local from = '<' .. tostring(settings.from) .. '>'

  -- message headers and body
  settings.source = smtp.message({
    headers = {
      to = table.concat(to, ', '),
      subject = subject,
      ['From'] = from,
      ['Content-type'] = 'text/html; charset=utf-8',
    },
    body = message
  })

  settings.from = from
  settings.rcpt = to
  res, err = smtp.send(settings)
  return res,err
end

4) Send a mail

Code:

subject = 'E-mail test'
message = 'Testing e-mail'
res, err = mail('yourrecipient@gmail.com', subject, message)
