Setting Up Your Custom Domain

You can send and receive email as you@yourdomain.com using Kerabie Mail as the backend. Here's how.

Prerequisites

• You own the domain (registered with Namecheap, GoDaddy, Cloudflare, etc.)
• You can edit the domain's DNS records
• A Pro or Premium plan (custom domains require a paid plan)

Step 1 — Add your domain

1. Log in and go to Settings → Domains.
2. Click Add domain and enter your domain name (e.g. example.com).
3. Kerabie Mail will show you a set of DNS records to add.

Step 2 — Add DNS records

Log in to your domain registrar and add the following records:

MX record (incoming mail)

SPF record (outgoing mail authentication)

DKIM record (signature verification)

Kerabie Mail generates a unique DKIM key for your domain. Copy the TXT record shown in the dashboard and add it to your DNS:

DMARC record (policy, recommended)

Start with p=none while testing, then move to p=quarantine, then p=reject once delivery is confirmed.

Step 3 — Verify

DNS changes typically take 5–15 minutes (up to 48 hours in rare cases). Return to Settings → Domains and click Verify — Kerabie Mail will check all records and show a green tick when ready.

Step 4 — Create a mailbox

Once verified, go to Settings → Mailboxes → Add mailbox, choose your domain, and create the address (e.g. hello@example.com).
