How do I make emails send from the correct address?

Posted August 2, 2014 8.2k views

Currently, emails sent with sendmail (using CodeIgniter’s email class) are being sent from noreply@d1stkfactory. Not only is this a weird looking email address—it causes the emails to end up in spam every time.

I set the from address in the code but it still sends from noreply@d1stkfactory.

I found this question:

The answer on it says to change the default hostname in /etc/mailname. It was indeed set to “d1stkfactory” so I changed it to the correct domain, I restarted sendmail and it still sends from noreply@d1stkfactory.

Does anybody know what could be causing this?

Try adding the following line to /etc/hosts:

then, set your droplet’s hostname to a FQDN (such as

echo | sudo tee /etc/hostname
sudo hostname -F /etc/hostname

finally, restart sendmail:

sudo service sendmail restart

Does that fix it?

  • Thanks for answering.

    I added that line to /etc/hosts, set the hostname to, and restarted sendmail but it still sends from noreply@d1stkfactory :/

    I even waited several minutes after restarting sendmail, yet it still sent from that address.

    Is there anything else that you know of that might be causing this?

may be you are using exim4 on a debian system. after changing /etc/mailname restart exim4 with:

sudo service exim4 restart
