And have the email sent without any confirmation or prompts to the user?
The reason is, I want to send a brief message via email to myself when a specific event happens in a java program. The idea is that I will use Runtime.getRuntime()… etc. to send the mail command from my java program.
I used cron to do something similar in the past, but the current implementation doesn’t use cron, so I need to try this out instead.
mail can represent quite a couple of programs on a linux system. What you want behind it is either sendmail or postfix. I recommend the latter.
You can install it via your favorite package manager. Then you have to configure it, and once you have done that, you can send email like this:
As far as configuring postfix goes, there’s plenty of articles on the internet on how to do it.
Unless you’re on a public server with a registered domain, you generally want to forward the email to a SMTP server that you can send email from.
