Csv file as attachment

[admin]

Use this. Put multiple recipients into the to table. The first email is the main recipient, all others will receive a copy. Separate CC header is not needed.

Code:

to = { 'first@example.com', 'second@example.com', 'third@example.com' }

subject = 'CSV'

smtp = require('socket.smtp')
mime = require('mime')
ltn12 = require('ltn12')

if type(to) ~= 'table' then
  to = { to }
end

for index, email in ipairs(to) do
  to[ index ] = '<' .. tostring(email) .. '>'
end

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

msgt = {
  headers = {
    ['To'] = to[ 1 ],
    ['From'] = from,
    ['Subject'] = subject,
    ['Content-Type'] = 'text/csv',
    ['Content-Disposition'] = 'attachment; filename="file.csv"',
    ['Content-Transfer-Encoding'] = '7BIT',
  },
  body = ltn12.source.string(csv)
}

settings.source = smtp.message(msgt)
settings.from = from
settings.rcpt = to

res, err = smtp.send(settings)
log(res, err)
