We have a requirement to send some research analysis mails as quickly as possible.
Everyday after the data is available my app generates the mails in eml format in a directory. These are personalized mails with attachments and have to reach the recipients "instantly" ( in my customers lingo ... Research reports are useless after the market opens ) What is the quickest way of pushing EML files to postfix for delivery. Currently I have a perl script that makes parallel smtp connections on localhost and sends the mails. Should I send the mails on command line. There are currently around 50k mails to be delivered ideally within 5-10 mins. I am only bothered about sending to postfix because delievery from there is already taken care of. Is there a better way , other than sending mails on command line or SMTP. Something like and API to inject into postfix maildrop. Thanks Ram
