How to set a new domain for tracking?

Oempro has a powerful “Delivery Servers” feature where you can set different SMTP servers and domains for user groups. In this way, you can split email deliveries across different SMTP servers based on user group reputation level (or purpose).

This will give you great power to control and manage your email delivery reputation. For example, if a user sends an email and causes a high amount of spam complaints (or hard bounces), this will not affect your other users.

Below, you can see an example Delivery Servers setup with multiple SMTP servers:

When creating a new delivery server, you have option to set tracking and sender domains:

With this feature, you can also establish “Domain Alignment” in your emails. To set a different domain for tracking and bounce handling, you need to make a few DNS setup on the new domain DNS control panel.

Let’s say, your Oempro is installed on domain. And let’s assume you are going to use “” as the new tracking domain on the delivery server. You need to set these DNS records for DNS control panel:


If you are going to setup a different sender domain, you also need to set a few DNS records to comply with SPF, DKIM and DMARC policies. Let’s say your sender domain is going to be You are going to set these DNS records:

  • TXT "v=spf1 ......... ~all;"
  • TXT "v=DMARC1; p=none;;; sp=quarantine; fo=1; pct=100; ri=86400; adkim=s; aspf=s;"

You also need to setup a DKIM record for your sender domain. To setup this, you need to contact your SMTP service provider and ask them to send you the public record for DKIM setup.

To enable local email relaying for bounce/fbl/reply tracking, edit /opt/oempro/system/.env file and add sender domain you have set above to the OEMPRO_BOUNCE_SMTP_LOCAL_DOMAINS constant.

Then restart the bounce processes. Run the following command on your server:

docker exec -ti oempro_bounce supervisorctl restart all

And lastly, you need to also make sure that SSL is activated for this new tracker domain. Otherwise, if you are using Oempro under SSL (https://), tracking will not work unless you generate SSL certificate for your new domain. To do this, please follow the instructions written here.

If you have any questions, let me know by replying. Happy to help always!

Thanks for this post.
Could you please post screenshots of the “Domains” tab to understand better how you set up these different delivery servers? (the screenshot above of the “Domains” tab shows an empty page only). Thanks a lot!

Having two records for (one TXT and one CNAME) produces an error. It’s not possible to do that presumably because CNAME is a kind of redirect and therefore no other record may be created for Instead, the TXT record should be set at
How do you see this?
Any help (or better: a full example with all settings at Oempro and also at the DNS-Server) would be greatly appreciated, we are still struggling with the settings… Thanks!

Hi @Jose_Cruset, yes, for CNAME records, you need to set TXT records under the pointed domain DNS.

What we usually set are;

That’s all.

Let me know if you have any questions.

Thank you for your reply. It does not work on our end (Oempro does not put the green checkmarks after checking the DNS Settings).
Our Oempro domain is (and the sender domain is However, Oempro is accessible (and also the license is registered under)
In your example above, should be or
And: is the additional subdomain (in your example m1) necessary?

Thanks a lot!

P.S.: In case you have a real live example (no dummy/example values) which is not confidential and can be shared here, it would help a lot.

Hi Jose, sure, let me share my personal setup here:

Oempro installed at:

Sender setup:

Please ignore checkboxes/crosses on your delivery server test results. They are done with a config in file. If it’s not done, it’s normal to get crosses. Just pay attention to the “SMTP test result”. It should be a green checkbox.

Based on your sender domain/oempro domain setup;

This would be an ideal setup. Jose, please get in touch with me directly in you need a more in-depth deliverability analysis.

How to disable the click tracking for specific Delivery server?

Sandeep, there’s no “delivery server” specific link tracking enable/disable option. You can disable specific links inside email by adding no-link-track class to any link inside the email. Hope this helps.
