multiple domain

Multiple domains on one IP — at no extra cost.

Use a different domain, or even a subdomain, for each purpose. It's a better way to communicate with your clients, and SMTPServer includes it with every dedicated IP.

How do you add a domain to your SMTP server?

One domain takes less than 5 minutes to set up. Here is the whole process.

1

Add your domain

Add the domain in your SMTPServer panel and choose the IP to configure it with. (Free accounts don't get the IP selector.)

2

Get DNS configuration

Within seconds the system generates the DNS records for your domain, ready to copy.

3

Add CNAME records

In your DNS provider, create CNAME records with the Host and Value data from SMTPServer. Keep TTL at default.

4

Verify and send

Back in SMTPServer, the domain flips from Pending to Active once DNS verifies — usually within 5 minutes.

Turn the proxy off

If your DNS provider offers a proxy option (like Cloudflare's orange cloud), switch it off for these records. Keep them DNS-only.

Allow propagation time

CNAME changes can take up to 72 hours to propagate, though they usually apply considerably sooner.

Check the record format

Type: CNAME. Name: the Host value from SMTPServer. Value: the Target value from SMTPServer. TTL: default.
