'mail' use problem from command line

Question

I didn't have mail installed before, so I've did it using:

apt-get install mailutils

After that I've tried to send a mail with this command:

mail -s "Ssubjects" [email protected]

But I see just this error message:

cannot send message: Process exited with a non-zero status

anyway I can't understand what is the problem. Should I configure something?

Thanks

Try:

sudo dpkg-reconfigure postfix

as proposed in the answer.
