mail doesn't work

Question

I'm new to GNU/Linux and I want to send e-mail to other users on my computer (specifically from root to david). I've searched on google and I have tried the following:

    # mail david
      Subject: some subject.
      The message ...
      ^D
      Cc:

But when I login on the system as david and type mail it says no mail for david.

Does mail work too for sending an email to a G-mail account?

Solution

You can send mail to your gmail account using:

$ mail -s "Subject" [email protected]
Body Text
^D
Cc:^D

If it doesn't work, then check if mail is installed.

$ which mail

If this command doesn't give anything, then mail isn't installed. To install:

$ sudo apt-get install mailutils
 OR
# yum install mailutils

etc ...

Thanks for the info @Kartik, but it was not enough. Finally I had to reconfigure the MTA with dpkg-reconfigure exim4-config and now it works perfectly.
