How to get `mail` on a CentOS 6 server (running postfix)

Question

On my old server, and most other devices I have run, there is a provided mail program.

On my new CentOS 6 server, running postfix as the MTA, I cannot send command-line email via mail - the tool is not there.

When running a yum whatprovides mail call, I get nothing helpful back:

$ yum whatprovides mail

 You can use "*/mail" and/or "*bin/mail" to get that behaviour

How is user-to-user mail supposed to be sent on CentOS 6?

Solution

In CentOS, this binary is provided by the mailx package:

yum install mailx

FYI, as the message at the bottom of your post indicates, you are using whatprovides incorrectly. Proper usage searching mirrors for a file called 'mail' would have been:

yum whatprovides */mail

yum whatprovides */mail or yum whatprovides *bin/mail?
