That’s a MUA (mail user agent). It needs an MTA (Mail Transfer Agent), too, else it has nowhere to send the mail.
For my sins, I usually install sendmail. Yes, I know its config file looks like heavily corrupted line noise, but you only need to make one change in it; the line that specifies the name of the “smarthost” - the place to send the mail onward - usually your ISP’s mail host.

What's the simplest (least config, lowest footprint) way to give a Linux box the capability to send email?
Just `mail` on it's own would do the job. It's probably already installed.
