With DKIM, digital signatures are added to email messages, for authorisation of the sender and authentication of the email itself. To create and validate DKIM signatures a pair of keys known as the public and private key must be created by the signer (the sender).
*Generate new DKIM key for new mail domain. If you or your customer prefer to use their own DKIM key, you can generate a new DKIM key and ask your customer to add DKIM DNS record. Refer to our tutorial to add DKIM DNS record. Generate new DKIM key (key length 1024) for new domain, and set correct file owner and permission.
*Open command prompt, use the following command to generate public key from the key generated in previous step (assuming it’s stored in c: private.key): openssl rsa -in c: private.key -pubout -out c: public.pem. Now you can use these 2 keys for your mail server and DKIM record!
*This online wizard is fine for generating keys for testing and evaluation. If you decide to use DKIM Core in production, though, you might want to consider the security risks. The wizard records your DKIM Core keys, including your private key, until you delete them.
*You need to generate a private and a public key for each of the domains for which you wish to sign mail. The private key is stored away on your server, while the public key gets published in your domain’s DNS records so that receiving mail servers can verify your DKIM-signed mail. You need decide now what the name of your selector is going to be.
DKIM (DomainKeys Identified Mail) is a method of signing electronic emails using public-private key. DKIM is used by receiving mail server for identifying email, that they are sent by authorized mail servers. It also minimizes the possibility of getting emails SPAM.
This tutorial will provide you a quick and easy way to set up DomainKeys with your POSTFIX running on CentOS and RHEL systems.
Generate Dkim Key PairHow DKIM Works ?
When we configured DKIM on sending servers. First, we generated a public/private key pair for signing outgoing messages. The public key is configured as TXT record on a domains name server, and the private key is configured in the outbound email server. When an email is sent by an authorized user of the email server, the server uses the stored private key to generate a digital signature of the message, which is inserted in the message as a header, and the email is sent as normal.Step 1 – Install DKIM-milter
First make sure you have enabled EPEL repository in your system. After that install dkim-milter package using following command.Step 2 – Generate Key Pair
Now create DKIM key pair using dkim-genkey command line utility provided by dkim-milter package. For this tutorial we are using domain name “example.com”, Change this name with your actual names. Free download z noise stereo.
Above command will generate two files default.private and default.txt. You can created multiple DKIM keys for different-2 domains and configure with your postfix server.
Now set the proper permissions on Keys directory.Step 3 – Configure OpenDKIM
Edit the Opendkim configuration file and Add/Update following entries in file.
Then edit the domain keys lists setting file /etc/opendkim/KeyTable and add following entry.
After that edit /etc/opendkim/SigningTable file and update following entry.
And edit /etc/opendkim/TrustedHosts file and update following entry.Step 4 – Configure Postfix
Now edit POSTFIX configuration file /etc/postfix/main.cf and add following values at the end of file
finally start DKIM service using following commandStep 5 – Configure DNS Entry
After configuring private key in postfix server. there will be another file /etc/opendkim/keys/example.com/default.txt/strong> generated by opendkim-genkey. Edit your DNS zone file and add this as TXT record found in default.txt. In my case this is like below.Step 6 – Verify DKIM
To verify that DKIM is working properly. Sonic 2 8 bit remake. Let’s send a test email through command line
In the received email in our mailbox, open the source of the email and search for ’DKIM-Signature’. You will find something like belowWhat is DKIM?
Domain Keys Identified Mail (DKIM) helps protect against email spamming and phishing attempts using your domain. It provides a method for validating a domain name identity associated with a message through cryptographic authentication.
DKIM uses a pair of keys, one private and one public, to verify messages.
A private domainkey adds an encrypted signature header to all outgoing messages sent from your email domain.
A matching public key is added to the Domain Name System (DNS) record for domain and email servers that receive messages from your domain use the public key to decrypt the message signature and verify the source of the signed message.Create a DKIM TXT record
The process of setting up DKIM involves items detailed in the following steps:
*Choose a DKIM selector.
*Generate a public-private key pair.
*Publish the selector and public key by creating a DKIM TXT record.
*Attach the token to each outgoing email.What is a DKIM selector?
A selector is specified as an attribute for a DKIM signature and is recorded in the DKIM-Signature header field.
Because DKIM selectors give different DNS query names, the system uses the selector as an additional name component for validation. Under each domain name, there might be one too many unique DKIM DNS records associated with different selectors.
Selectors enable multiple keys under a domain name, which can provide separate signatory controls among departments, date ranges, or third parties acting on behalf of the domain name owner. No two services or products should use the same selector.
A selector can be anything you want, such as a word, number, or a string of letters and numbers.
For example, if you choose oct2019 for your selector, the domain name would become oct2019._domain.example.com.Before you begin
Before you log in to the control panel and create a DKIM record, there are a couple of things that you need:
*Choose a simple, user-defined text string to be your DKIM selector. The selector is appended to the domain name to help identify the DKIM public key. See the previous section for more information about choosing a DKIM selector.
*Generate a public-private key pair by using a tool such as ssh-keygen on Linux or PuTTYgen on Windows. For help creating key pairs, see this article Generate RSA keys with SSH by using PuTTYgen.Steps on how to create a DKIM TXT record
Keep in mind that every domain provider should have specific steps for setting up DKIM in their platform. These should be relatively easy to find with a Google search.
Here is the basic outline:
*Generate the domain key for your domain.
*Add the public key to your domain’s DNS records. Email servers can use this key to verify your messages’ DKIM signatures.
*Turn on DKIM signing to start adding a DKIM signature to all outgoing messages

*Sender Policy Framework (SPF) - SPF specifies which domains can send messages for your organization.
*Domain-based Message Authentication, Reporting & Conformance (DMARC) - DMARC specifies how your domain handles suspicious emails.
