How to send mail from localhost in ubuntu 14.04

Question

Hello I have tried these command but I am not able to send mail please help me out..

1) Install sendmail

Sendmail might already be installed, but just in case, enter this into the server terminal:

sudo apt-get install sendmail

2) Configure sendmail

Enter the following command into the terminal and type "Y" for each question it asks:

sudo sendmailconfig

3) Edit hosts file

Time to edit your server's hosts file, access it by entering the following command into the terminal:

sudo vim /etc/hosts

Add the following line to the top of the file and save it:

127.0.0.1 localhost localhost.localdomain your_domain_name_here.com

Comment out any duplicate lines that already existed.

4) Restart apache Let's restart your server just for good measure. At this point emails sent via PHP's mail() function should be sending successfully and without much delay.

sudo service apache2 restart 

I didn't understand the 3rd step because I am working on localhost so how I can add domain name here..

Any help will be appreciable

Solution

your_domainname_here is used for virtual host . So if you are not creating virtual host simply run this command

sudo vim /etc/hosts

and add

127.0.0.1 localhost localhost.localdomain

restart your server

service apache2 restart

hope it will help you
