I know there is the command
mail [email protected] [subject] [body]
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
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:
echo "My message" | mail -s subject [email protected]
See the manual for more information.
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.
For gmail, for example, follow
or any other similar tutorial.
