Setting Up iRedMail with Digital Ocean

Hi. It’s my first time using digital ocean so forgive me for a noob question.

I’m currently setting up iRedMail with digital ocean. I’ve followed Step 1 and Step 3 of the instructions in “https://www.digitalocean.com/community/articles/how-to-install-iredmail-on-ubuntu-12-04-x64”

My hostname is “iredmail-testEmailServer” and i put “iredmai” on /etc/hostname. In my /etc/hosts I put “127.0.0.1 iredmail-testEmailServer iredmail localhost locahost.localdomain”

After performing those things and running “bash iRedMail.sh” the following error shows up: “Please configure a fully qualified domain name (fqdn) in /etc/hosts before we go further.”

My question is, why does it return the error above even when I’ve provided my FQDN in /etc/hosts?

Thanks in advance.

Hey kikorugeria, Your first entry in /etc/hosts doesn’t actually include a fully qualified domain name (“iredmail-testEmailServer” is just the short hostname, a FQDN would look like “iredmail-testEmailServer.example.com”).

Is “iredmail-testEmailServer” the name of your droplet? If so, it isn’t immediately relevant to the configuration inside.

Try this:

Have ‘iredmail’ in /etc/hostname

This means the short hostname of your droplet is simply ‘iredmail’

and in /etc/hosts have

127.0.0.1 iredmail.example.com localhost localhost.localdomain

This would make your FQDN for the host to be ‘iredmail.example.com’

If you were planning on using your own domain you could change example.com to whatever you domain is, for example iredmail.kikorugeria.com (this would also require configuring your domain name in digital oceans admin panel)

You can verify that the FQDN is correct by running the following command:

hostname -f

which should display ‘iredmail.example.com’ (or similar) and not just ‘iredmail’.

After this you should be able to run iRedMail.sh

Hope this helps!
