E-mail backup file

[manos@dynamitec]

Hello All,

I am trying to figure out how to send the backup file to more than one recipients using this script without success.

How would this part of the script look like if I want to send the mail to two, three ... recipients?

Code:

--Recipient for e-mail
to = 'example@hotmail.com'
alias_to = ''

--Subject for e-mail
subjectpart1 = 'MainSL Back-up file'
subjectpart2 = ''

image_description = 'Backup from MainSL'

--Message on bottom of email (will only be showed when client don't understand attachment)
epilogue = 'End of message'

--***********************************************************--
--******************** End of parameters ********************--
--***********************************************************--
--********** DON'T CHANGE ANYTHING UNDER THIS LINE **********--
--***********************************************************--

--Create table to include mail settings
local settings = {
    from = from,
    rcpt = to,
    user = user,
    password = password,
    server = 'smtp-mail.outlook.com',
    port = 587,
    secure = 'starttls',
}

--Create attachment
src = 'MainSL_backup-' .. os.date('%Y.%m.%d') .. '.tar.gz'
dst = '/home/ftp/' .. src

-- prepare files for backup
os.execute('sh /lib/genohm-scada/web/general/backup.sh')

-- create archive
os.execute('cd /lib/genohm-scada/storage && tar -c -z -f ' .. dst .. ' ./')

--Create subject
subject = subjectpart1 .. ": " .. src .. " " .. subjectpart2

--Load required modules to send email with attachment
local smtp = require("socket.smtp")
local mime = require("mime")
local ltn12 = require("ltn12")

--Create e-mail header
settings.source = smtp.message{
headers = {
          from = '' .. alias_from .. ' ' .. from .. '',
          to = '' .. alias_to .. ' ' .. to .. '',
          subject = subject
},

Any input on the solution would be apreciated.

Regards
