Background The solution described below uses the 'socket' package. Detailed documentation on the package can be found here: http://w3.impa.br/~diego/software/luasocket/smtp.html No further installation is needed since 'socket' is part of EXASOLs distribution. Solution using a Lua Script CREATE LUA SCRIPT "SEND_MAIL" () RETURNS ROWCOUNT AS smtp = require ( 'socket.smtp' ) sender = 'service@exasol.com' receivers = { 'captain.exasol@exasol.com' } -- use a dictionary message_text = 'hello world' -- put the message contents into a dictionary : mesgt = { -- SMTP headers headers = { to = 'Captain EXASOL <captain.exasol@exasol.com>' , from = 'EXASOL Service <service@exasol.com>' , subject = 'The mail you requested' }, -- message body body = message_text } -- send mail using an SMTP server res, err = smtp.send{ from = sender, rcpt = receivers, source = smtp.message(mesgt), -- you have to know/ask for the correct mail server, our cluster does not know any . -- if the cluster has no DNS service, you need to use an IP address server = 'mail.exasol.com' } if err then error(err) end / Additional Notes Ideas / Extensions Provide Parameters for all parts of a mail like receiver(s) subject text
