[Ubuntu 14.04 LAMP] Installed sendmail -- fatal error when I sent first message
OS: Ubuntu 14.04
I followed Jonathan’s instructions from from this post.
I created a test email and saved it at
I tried to send a test email from a text file to my Yahoo email account using this command:
sendmail firstname.lastname@example.org < /tmp/email.txt
The process completed.
When I logged back in, it said I had mail.
I installed mailutils to read the mail. It was a returned message saying sendmail couldn’t send the message and it mentioned a fatal error.
Here is the complete message:

I noticed the return-path is roy@roypenroddotcom. I named my host roypenroddotcom because it’s hosting my own personal site, roypenrod.com.
I’m very new to Linux, so I didn’t know the hostname would affect this. How do I change it so my email address is actually email@example.com?
Why did the sendmail fail? Was it the incorrect email address? Did I set something up wrong? Do I need to configure sendmail?
Any help you can give me is very much appreciated.
