Warning.png WARNING
This is recommended only for advanced users, proceed with caution.


This can be used to send mails from your HDA and to receive system emails.
To receive emails meant for the root user, you have to Forward System Emails after finishing this tutorial.

Install postfix and remove sendmail:

bash code
​sudo apt-get -y postfix mailutils sudo apt-get -y remove sendmail​


NOTE: During install of postfix, a popup box may display. If it does, select OK and then Internet. Add your domain name (i.e. home.com) and then select OK.

Execute the following to update /etc/postfix/main.cf:

bash code
​sudo postconf -e 'relayhost=gmail-smtp-in.l.google.com' sudo postconf -e 'smtp_sasl_auth_enable=yes' sudo postconf -e 'smtp_sasl_password_maps=hash:/etc/postfix/sasl_passwd' sudo postconf -e 'smtp_sasl_security_options='


Create /etc/postfix/sasl_passwd file with your Gmail login credentials that looks like below:

Text
​gmail-smtp-in.l.google.com user@gmail.com:password​

Obviously, you need to change user to your username and password to your gmail password.

Create the password database:

bash code
​sudo postmap hash:/etc/postfix/sasl_passwd​


Protect the files with your Gmail login data:

bash code
​sudo chown root:root /etc/postfix/sasl_passwd sudo chmod 600 /etc/postfix/sasl_passwd​


Restart Postfix:

bash code
​sudo /etc/init.d/postfix restart​


Now try sending a mail, it should reach your Gmail account (change user to match your account name):

bash code
​echo "This is Content" | sudo mail -s "This is subject" user@gmail.com​


Check the mail log:

bash code
​tail -f /var/log/mail.log​


If all goes well, you should not see any errors.
