Email Management: Domain Authorization for sending email
This service allows you to authorize the sending of emails from email accounts created in a hosting so that you can send on behalf of an external domain.
This allows you to authorize external domains that are not in your cdmon user so that they may be authorized to make these shipments. This guide shows how to access and manage domain authorization from the dashboard.
First of all you must access hosting management where you want to add this authorization. In the "Email" section you should go to "Domain authorization"
Upon accessing there will appear the list of domains already authorized or pending authorization in that hosting. To start the process you must go on "Add domain":
From this screen adds the domain name you want to add:
At the time you add the domain, the dashboard will display a message like the following, indicating the steps to take to validate this domain:
Once you accept the message, we will return to the list of authorized domains and we will be able to see the domain that we have placed as pending validation. You can reopen the validation window if you have not copied it before, you must click on the logo in the "Actions" section:
It will again open the window to verify domain ownership. Now is the time to do the process of creating a TXT record with the text that appears to it. You must do so in the DNS management of the external domain. How to set up a TXT record
To create the registry you must access the DNS management of this hosting, from the basic list of services you can access:
From here you can see all the DNS registers created in your domain. In this case you must click on "New Record" and you have to create a TXT record with the value that the dashboard has been copied in the previous step:
Note: It is very important to create the TXT record under the subdomain of domauthvalidation as shown in the image, but the dashboard will not be able to find this information.
When the record has been created and propagated (you must leave several minutes/hours to spread) you will already be able to verify ownership of the domain. You must access the same window to verify the domain and click on the "Verify" button
If all steps are done correctly, the domain is added to the list of domains authorized for that hosting:
How to add authorized email accounts
Once you already have the domain authorized to send mail under that hosting, the email accounts to be authorized must be added. To do this, you must only go in the logo of the "Actions" section that has enabled:
From there you must manually type the name of the accounts you want to add and click on "save" to apply the changes:
If it detects them, the dashboard will show that you have added the email accounts correctly:
Finally, if you want to delete a list domain from those authorized to send mails from that hosting, you must only go to the list of domains and go to the action column to the last emoticon of all, the red cross. You must reaffirm that you wish to continue:
Scenarios and conflicts with authorized shipments
If you do not correctly set up the registration with your respective TXT and thus validate the email account external to their primary domain, you will find that at the time of sending the emails you may receive an error with the SMTP output server. Example of error sending an email from Roundcube without correct validation:
Another situation may be to receive a message from "Sender address rejected" if you try to respond from a different address to that which you receive an email.
5.7.1 : Sender address rejected: not owned by user direccionconfigurada@cdmon.comTo avoid security problems in responding to emails, it is important to do so from the address where it is received, i.e. avoid modifying the FROM (original address) to answer the mail under a different name.
