Question

How do I make emails send from the correct address?

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: https://www.digitalocean.com/community/questions/debian-configuring-sendmail-and-php-mail-cannot-change-from-address

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, gifavs.com. I restarted sendmail and it still sends from noreply@d1stkfactory.

Does anybody know what could be causing this?

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

sudo service exim4 restart

Try adding the following line to /etc/hosts:

127.0.0.1 gifavs.com

then, set your droplet’s hostname to a FQDN (such as gifavs.com):

echo gifavs.com | sudo tee /etc/hostname
sudo hostname -F /etc/hostname

finally, restart sendmail:

sudo service sendmail restart

Does that fix it?
