Email is an essential tool in our lives, as well as being one of Evicertia's primary methods of communication, but it is also a common target for spam and fraud. To counter this, there are three important defences: SPF, DKIM and DMARC. These technologies work together to ensure that emails are authentic and secure. From verifying senders to digital signatures and security policies, these solutions are essential to protect our electronic communications and strengthen our email security.

Brief Introduction to SPF and DKIMThe first step in this help is to explain these email security measures in order to understand how they work. What is SPF?SPF (Sender Policy Framework) is a technique that helps prevent spam or fraudulent e-mail by verifying whether the mail server sending a message is authorised to do so on behalf of a specific domain. Step-by-step explanation:
(Flowchart of a domain verified by SPF) What is DKIM?DKIM (DomainKeys Identified Mail): is another technique that helps to guarantee the authenticity of emails by adding a digital signature to the message. Step-by-step explanation:
(Flowchart of a domain verified by DKIM) What is DMARC?DMARC (Domain-based Message Authentication, Reporting, and Conformance) is like an email supervisor for a domain (such as "mydomain.com"). Think of it as a set of rules that the domain owner sets up to tell other mail servers how to handle emails that appear to come from their domain.

How to set up a Forwarding Domain?A verified forwarding domain allows you to send EviMails with an email account from that domain with the security of delivery as the SPF and DKIM settings are verified. To set up a forwarding domain, it must be registered on your site with an Administrator user. Only Site Administrators will be able to register domains. The registration and configuration of domains is done from the "Management of sender e-mail addresses" screen, which can be accessed from the top menu "My Data". |
...
Grid of forwarding domainsThis screen shows the domains that have been configured on a given site. These domains appear in a Grid divided into 7 columns
|
...
Registration of a referral domainBy clicking on the "Add domain" button, a modal screen is displayed to start the configuration of a new domain. In this first step, the user is reminded that he/she must have access to the DNS settings of the domain he/she intends to configure, and the recommendation to use subdomains. |
...
Verifying the domainThis is the next step in the domain registration process. In this step the user is shown the necessary configurations that must be made in the DNS of his domain so that it can be verified. These configurations are customised with the domain entered in the previous step. To make it easier for the user to enter data into their systems. Once the user has made the necessary modifications to the DNS file of his domain, he has the option to verify the domain by clicking on the "Verify domain" button or Exit the process by clicking on "Cancel". The user is also given the option to create his own DKIM selector for that domain, by clicking on the button "Add custom key" a popup window will open to generate the selector and the pair of keys (private and public) this option will be detailed further on. |
...
SPF configurationThe SPF record of the client's domain server must contain the mention of our server _spf.evicertia.com, for example as follows:
DKIM configurationThe DKIM record must contain one of the following settings. Depending on whether you have set your own selector or the two Evicertia shared selectors.
