How do I create a Droplet without a private IP?
You can disable the address on your Droplet from the command line or through updating your Droplet’s eth1 interface configuration.
Why is SMTP blocked?

SMTP ports 25, 465, and 587 are blocked on Droplets to prevent spam and other abuses of our platform.
Even if SMTP were available, we strongly recommend against running your own mail server in favor of using a dedicated email deliverability platform. Dedicated email deliverability platforms are better at handling deliverability factors like IP reputation.
To send mail from DigitalOcean, we recommend using SendGrid via the SendGrid Marketplace 1-Click App.

Ensure your Droplet’s public and private network interfaces are correctly named eth0 and eth1.
Can I have more than one domain on the same Droplet?
Yes, you can point an unlimited number of domains to a single Droplet, and you can serve multiple websites from a single Droplet.
