How to use your own domain with KM0 Mail

Add your domain, publish the DNS records, verify it, and create your own email addresses, step by step.

Introduction

With KM0 Mail you can receive and send mail from your own domain, for example name@yourdomain.com. Everything is managed from webmail, with nothing to install.

Before you start

What you need

  • A KM0 Mail account: if you do not have one yet, follow the create account tutorial.
  • Your own domain: one you already have registered (for example with your domain provider).
  • Access to the DNS records: your provider's panel where MX and TXT records are edited.

Step 1

Open Settings, My domains

  1. Sign in at https://mail.km0digital.com/.
  2. Open Settings and go to the My domains section.

Step 2

Add your domain

  1. Type your domain (for example yourdomain.com).
  2. Click Add.
  3. It appears in the list as pending, with its DNS records.

Step 3

Publish the DNS records

Open your domain provider's panel and copy each record shown by KM0 Mail. Use the Copy button to avoid mistakes.

  • TXT (ownership): confirms the domain is yours. Copy the exact host and value from the panel.
  • MX: routes incoming mail to mail.km0digital.com with priority 10.
  • TXT (SPF): authorizes sending: v=spf1 mx a:mail.km0digital.com ~all.
  • TXT (DKIM): at host mail._domainkey, with the key shown in the panel.

Step 4

Verify the domain

  1. Return to My domains and click Verify.
  2. Each record turns from pending to OK once it is detected.

DNS changes can take from a few minutes to 48 hours to propagate. If they do not show yet, wait a bit and click Verify again.

Step 5

Create addresses on your domain

Once the domain is active, you can create email addresses.

  1. On your domain, click Addresses and then Add address.
  2. Type the username (for example hello) to create hello@yourdomain.com.
  3. Set a password for that address and save.

Step 6

Sign in with the new address

  1. Go to https://mail.km0digital.com/.
  2. Enter the full address (for example hello@yourdomain.com) and its password.
  3. Click Sign in.

Common problems

Troubleshooting

  • Verification does not pass: check that host and value match the panel and wait for DNS to propagate.
  • Cannot add addresses: verify the domain first; addresses can only be created once it is active.
  • Domain already in use: another account registered it; use a domain you own.
