Are you using gmail? If yes did you created an app password in your gmail account and use that in your script?

  local settings = {

    -- "from" field, only e-mail must be specified here

    from = 'nguenangulrich6@gmail.com',

    -- smtp username

    user = 'nguenangulrich6@gmail.com',

    -- smtp password

    password = '***',

    -- smtp server

    server = 'smtp.gmail.com',

    -- smtp server port

    port = 465,

    -- enable ssl, required for gmail smtp

    secure = 'sslv23',

  }

  -------------------END OF USER EDITABLE AREA---------------------

  local smtp = require('socket.smtp')

  local escape = function(v)

    return '<' .. tostring(v) .. '>'

  end

  -- message headers and body

  settings.source = smtp.message({

    headers = {

      to = escape(to),

      subject = subject,

    },

    body = message

  })

  -- fixup from field

  settings.from = escape(settings.from)

  settings.rcpt = { escape(to) }

  return smtp.send(settings)

Yes, like in the above message

RE: email sending - admin - 07.05.2025

You need to enable 2FA and the create app password: https://myaccount.google.com/apppasswords
When adding password to your script remove all spaces so only 16 characters are left.

Thank's, it's OK now

RE: email sending - JuLopez - 27.11.2025

Morning to everyone,

I tryed to do the same script, in my Comm Funct, I have:

Code:
function mail(to, subject, message)

  -- make sure these settings are correct

  local settings = {

 --    "from" field, only e-mail must be specified here

    from ='al*******@gmail.com',

    -- smtp username

    user = 'LM********',

    -- smtp password

    password = '********',

    -- smtp server

    server = 'smtp.gmail.com',

    -- smtp server port

    port = 465,

    -- enable ssl, required for gmail smtp

   -- secure = 'tlsv1_2',

    secure = 'sslv23'

  }

  local smtp = require('socket.smtp')

  local escape = function(v)

    return '<'..tostring..'>'

  end

--  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, ', '),

        to = escape(to),

        subject = subject,

        --['From'] = settings.from,

        ['From'] = from,

      ['Content-type'] = 'text/html; charset=utf-8',

    },

    body = message

  })

  -- fixup from field

  --settings.from = '<' .. tostring(settings.from) .. '>'

 -- settings.from = from

  settings.from = escape(settings.from)

  --settings.rcpt = to

  settings.rcpt = { escape(to)}

  return smtp.send(settings)

end

And in my Event-Script I have:

Code:
curr_value = event.getvalue()

prev_value = storage.get('prev_value')

if curr_value == prev_value then

  return

end

storage.set('prev_value', curr_value)

os.sleep(10)

if curr_value then 

  subject = 'Main switch = PERMIT'

  message = '\nState: Desbloqueado'

else

  subject = 'Main switch = PROHIBIT'

  message = '\nState: BLOQUEADO!!'

end

mail('ju*********@gmail.com', subject, message)

The problem is that when I Run my Event script, I don't have any Log or Error, but I neither recive any e-mail in my account.
I will appreciate the help!

RE: email sending - admin - 27.11.2025

Use this to get the result/error in Logs tab.

Code:
res, err = mail('ju*********@gmail.com', subject, message)

log(res, err)

Don't randomly change the mail() function. You only need to change the settings table, everything else should be kept as is. In your case the 'From' header is invalid because the assigned variable is not defined.

Thanks for the point. I forgot to include the log, but when I run the script again, I get no response from either the log or the error log, even though I added the log before running it. I'm also not receiving the email. I've also removed the "From" from the message body, so it now looks like this (in Comm Func) :

Code:
function mail(to, subject, message)

  local settings = {

 --    "from" field, only e-mail must be specified here

    from ='al************@gmail.com',

    -- smtp username

    user = 'LM**********',

    -- smtp password

    password = 's************',

    -- smtp server

    server = 'smtp.gmail.com',

    -- smtp server port

    port = 465,

    -- enable ssl, required for gmail smtp

   -- secure = 'tlsv1_2',

    secure = 'sslv23'

  }

  local smtp = require('socket.smtp')

  local escape = function(v)

    return '<' .. tostring .. '>'

  end

  -- message headers and body

  settings.source = smtp.message({

      headers = { 

        to = escape(to),

        subject = subject,

    },

    body = message

  })

  settings.from = escape(settings.from)

  settings.rcpt = { escape(to)}

  return smtp.send(settings)

end

RE: email sending - admin - 27.11.2025

From header is required, mail sending won't work without it. Temporarily modify the event script so it only sends the email without checking the previous value and waiting for 10 seconds.

Almost fixed, now it's sending me the same error that the collegue:

Quote: * string: 535-5.7.8 Username and Password not accepted. For more information

I already change the user name and the password, I delete the spaces from the password and give the same name that I use when i create the app password, the "app name"

RE: email sending - admin - 27.11.2025

Username should be the same as the sending email (from), including @gmail.com
The app password should be 16 characters without spaces.

Thank you very much!
It's working! Smile
