Setting up email on your Raspberry Pi is relatively easy using Gmail as an SMTP server.
If you have installed WordPress then you will need email to allow new users to register and add comments.
In the terminal:
sudo apt-get install ssmtp
sudo apt-get install mailutils
sudo apt-get install mpack
sudo apt-get install mailutils
sudo apt-get install mpack
Setting the configuration for ssmtp:
sudo nano /etc/ssmtp/ssmtp.conf
Now add the following to your file:
AuthUser=youruserid@gmail.com
AuthPass=userpass
FromLineOverride=YES
mailhub=smtp.gmail.com:587
UseSTARTTLS=YES
AuthPass=userpass
FromLineOverride=YES
mailhub=smtp.gmail.com:587
UseSTARTTLS=YES
AuthUser is the Gmail account that you are going to use.
AuthPass is the Gmail user password
To test the email do the following:
echo “body” | mail -s “Subject” toaddress@somwhere.com
where toaddress@somwhere.com is the to address that we want to send to and press return.
