I have a couple of scripts that use the linux “mail” command to send results of cron jobs, backups, and such. The problem is I don’t want to setup more overhead than I need, nor do I want to setup non-secure services. So after asking the guys on the #uphpu channel, they recommended postfix. So for a Ubuntu 10.04 server, just run the following commands:
aptitude install postfix #when prompted, select Internet Site
aptitude install mailutils
Then bingo, the mail command should work. You can test it by doing:
mail justin@example.com
It will ask for any Cc addresses, and a subject. Then, type your message, and when you are done hit “Ctrl-D” for done.
