We have a custom based hardware running Linux. It generates a daily report by a script which is executed by cron.
Our requirement is to have all the devices on the private network send an email with this daily report (.txt) file as an attachment.
I have installed postfix as a SMTP Server on one of the machine. I am not getting any idea of how I can proceed to the next step which I believe is creating accounts ( emailid/password ) and I have email client ( mutt ) installed on the other devices.
How can I proceed or what are the steps required to achieve my requirement
