I always seem to struggle with this most simple of configuration tasks!
Starting from a clean install of (say) Ubuntu/Debian, and with a set of SMTP server credentials in your hand, what's the best/simplest way to get email set up so that emails from cron jobs get sent, and so that there's a minimal "mail" client at the commandline?
I don't want the overheads of postfix + MySQL that things like mailutils bring in. (Or maybe I should accept those overheads?)
The broader objective is that I can set the recipient address for email to root or other users, and the sender address from which emails get sent by default.
