sudo apt-get install mailutils
sudo apt-get install postfix

and

sudo nano /etc/postfix/main.cf

inet_interfaces = all
change to:
inet_interfaces = localhost

sudo service postfix restart

echo "This is the body of the email" | mail -s "This is the subject line" [email protected]


sudo nano /etc/aliases

 # See man 5 aliases for format
 postmaster:    root
 root:          [email protected]

@Dawid-Glomba Good advice, but I don't think it will do anything, he's using SparkPost, not postfix.

That said, something is wrong with your SparkPost. It is failing back to the local address because SparkPost is not working.

The invalid domain message is coming from SparkPost, because you have not properly set up your DNS records.

Following these instructions should fix it for you.

Have you set the email settings in the admin panel?
