Unable to send a email through the command line on (Ubuntu Desktop)

Question

I'm trying to send a email from my Ubuntu:

 mailx -s "This is all she wrote" < /dev/null something@fdsfds.com
 or
 mail -s "hfdsfds" something@fdsfds.com

And nothing has happened at all. No email. Why not?

Is it matters, it's my local computer, not a remote server.

Cannot suggest how to solve this, but i personally use mutt from time to time. An easy to configure app. Might need to search the interwebs on how to configure it for a bit. Let me know if you want to see my config — Sergiy Kolodyazhnyy, Feb 12 '16 at 05:48
Obviously not a duplicate, as the answers to that other question do not say what do to in case of errors. What are the contents of mail.log (and possibly also mail.err)? — fkraiem, Feb 12 '16 at 05:53
@fkraiem, it says "open /etc/postfix/main.cf: No such file or directory" — Oskar K., Feb 12 '16 at 08:59
So you have installed Postfix? How did you install it? If you only want to be able to send email through an external SMTP server (such as the one provided by your ISP), you can install ssmtp, which is much easier to configure. — fkraiem, Feb 12 '16 at 09:01
are you tring to send email to remote server(like gmail)? do you have Internet on your local machine? — gaganyaan, Feb 12 '16 at 09:02

I routinely send email from within Ubuntu using the command line using mailx and gmail, perhaps this will be useful for you?

Create the file: $HOME/.mailrc by running:

touch $HOME/.mailrc

Then open this file with your favourite text editor and add the following:

#---------------------------#
# Setting mailx for gmail!! #
#---------------------------#
set smtp-use-starttls
set smtp-auth=login
set smtp=smtp://smtp.gmail.com:587
set from="your_gmail_username@gmail.com"
set smtp-auth-user=your_gmail_usernameg@gmail.com
set smtp-auth-password=your_gmail_password
set ssl-verify=ignore
set nss-config-dir=/etc/ssl/certs

Remember to use your own gmail username and password, and making sure you have installed the Ubuntu ca-certificates package. Then you can send email easily from the command line as follows:

echo "Testing, Testing, Testing" | mailx -s "My test..." someone@whatever.com

The $HOME/.mailrc could easily be configured for other mail servers if you don't have a gmail account, but using gmail in this way means not having to bother with Postfix and friends.

Below is a test, demonstration email using a verbose setting, I have masked the email address as it is my own:

andrew@ilium~$ echo "Testing, Testing, Testing" | mailx -v -s "My test..." xxx@gmail.com
