Send mail through Lua

Question

I want to send a simple mail in Lua, I used the example in official documentation, and always give me back nil. Example:

-- load the smtp support
local smtp = require("socket.smtp")

from = "<[email protected]>"

rcpt = {
  "<[email protected]>",
  "<[email protected]>",
  "<[email protected]>"
}

mesgt = {
 headers = {
   to = "Fulano da Silva <[email protected]>",
   cc = '"Beltrano F. Nunes" <[email protected]>',
   subject = "My first message"
},
body = "I hope this works. If it does, I can send you another 1000  copies."
}

r, e = smtp.send{
 from = from,
 rcpt = rcpt, 
 source = smtp.message(mesgt)
}

Says:

host or service not provided, or not know

Answer 1

Maybe this can help:

-- load the smtp support
local smtp = require("socket.smtp")

from = "<[email protected]>"

rcpt = {
  "<[email protected]>",
  "<[email protected]>",
  "<[email protected]>"
}

mesgt = {
 headers = {
   to = "Fulano da Silva <[email protected]>",
   cc = '"Beltrano F. Nunes" <[email protected]>',
   subject = "My first message"
},
body = "I hope this works. If it does, I can send you another 1000  copies."
}

r, e = smtp.send{
 from = from,
 rcpt = rcpt, 
 source = smtp.message(mesgt)
 user = "usuario_valido_em_algum_servidor_de_email_que+voce_tenha_acesso",
 password = "senhaqui",
 server = "servidor_smtp_onde_voce_tenha_acesso_smtp.google.com_por_exemplo",
 port = 465, -- pode ser outra porta
 create = sslCreate
}

I put in the Github for future reference.

I do not know if I would send it without encryption in this case. I do not know if this library is complete. She doesn’t say anything about SSL and without this protocol it will be difficult to use any server nowadays.

If you read the documentation, you will see that there are other things that need to be done. Just copying done example does not solve everything. You have to study existing material and adapt to what you need.
