Email sending do not work

[Tue]

Hello There 

I'm new to this forum, and also a littel new to scripting in luna.

I have a Schneider HomeLynk with Wiser for KNX on. I'm trying some very simple thinks regarding sending Email. but I seams to have no luck getting ANY mail send what so ever.

I have now mad a new Gmail accound, and on that on enabled "allow acces for less secure apps" and changed nothing else than that on Gmail side

in script I have changed this to my new settings i common functions:

Code:

  local settings = {
    -- "from" field, only e-mail must be specified here
    from = 'MYEMAIL@gmail.com',
    -- smtp username
    user = 'MYEMAIL@gmail.com',
    -- smtp password
    password = 'MYCODE',
    -- smtp server
    server = 'smtp.gmail.com',
    -- smtp server port
    port = 465,
    -- enable ssl, required for gmail smtp
    secure = 'sslv23',
  }

And in my triggered function i have this:

Code:

-- make sure mail settings are set in user function library before using this function
subject = 'There is new mail'
message = 'Med Venlig Hilsen Kastaniely'
mail('TEST@InoDes.dk', subject, message)

But nothing comes to my Emil, how do I debug that? and any good ideas what to do?

Log what the server reply is:

Code:

res, err = mail('TEST@InoDes.dk', subject, message)
log(res, err)

Log what the server reply is:

Code:

res, err = mail('TEST@InoDes.dk', subject, message)
log(res, err)

Which FW do you have? You need to change secure = 'sslv23', to secure = 'tlsv1_2',

How do I check if it can se the internet? It sams like 0.dk.pool.ntp.org do not work either (Just seen that the system clock has driftet)

[Erwin van der Zwart]

Hi,

Did you enabled "less secure apps" in your gmail account? If not you will not be able to send mail..

To check your internet you can open the appstore or do a ping from the network tools..

Erwin

 Yes I did

Check if you have DNS and gateway set correctly in Network interfaces, You can ping google.com form Network utilities in Status

[Tue]

I can from the system ping 8.8.8.8 (Google) and that works..

Replace the whole email function as it sound as you were upgrading an old device and then old libraries are preserved.

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 = 'example@gmail.com',
    -- smtp username
    user = 'example@gmail.com',
    -- smtp password
    password = 'mypassword',
    -- 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

  return smtp.send(settings)
end

Is there anything else in system, I can check (It has newer been able to send Email, have tryeid many times to get it to work). Any port in my Network (IP) that has to be speciel or anything else on server that can block it?

[admin]

"Try again" error usually means that DNS resolve failed for some reason. Check that you have valid DNS set in Network > Interfaces > eth0.

Hello,

I am trying to send email with above code but not successed. The ping is ok from LM to for example www.google.com. I have enabled less secure apps on the gmail account.

I have tried both of sslv23 and tlsv1_2 for secure. The log as below.

* arg: 1
* nil
* arg: 2
* string: timeout

[Daniel]

Can you access our app store from this LM?
