Check that settings.rcpt in the mail() function is present and to is not empty.

Don´t see that it is,  heres the mail() function script

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 = 'xxxxx',     -- smtp username     user = 'xxxxx',     -- smtp password     password = 'xxxxx',     -- smtp server     server = 'smtp01.binero.se',     -- smtp server port     port = 465,     -- enable tls, required for gmail smtp     secure = 'sslv23',   }   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

A possible cause is that "from" field contains a non-existing address. Also some servers require "POP before SMTP" authentication method which is not possible with LM.
