Is DKIM a TXT record?
A domain owner also adds a DKIM record, which is a modified TXT record, to the DNS records on sending domain. This TXT record will contain a public key that’s used by receiving mail servers to verify a message’s signature.
What is a DKIM record?
DKIM stands for DomainKeys Identified Mail and is used for the authentication of an email that’s being sent. Like SPF, DKIM is an open standard for email authentication that is used for DMARC alignment. A DKIM record exists in the DNS, but it is a bit more complicated than SPF.
Why is my DKIM not valid?
When we receive an email that has a DKIM signature, we redo the encryption and hashing of the email and compare the result with the given signature. As a result, if the two signatures don’t match, it means the content was altered and the email is discarded with an “Invalid DKIM Signature” message.
How do you add a DKIM record in WHM?
Log into WHM. In the search bar above the left navigation, search for “DNS.” Then, click on Edit DNS Zone. Click on the domain where you auto-generated the DNS record in cPanel, then click Edit. Scroll down and check to see that your DKIM records are included.
What is txt SPF?
An SPF record or SPF TXT record is a record that is part of your domain’s DNS — similar to a DMARC record. It contains a list of all the IP addresses that are permitted to send email on behalf of your domain. If it is, then a link has been established between the piece of email and the email domain.
Is DKIM TXT or Cname?
Setting up DKIM The key will either be inserted directly into your zone as a TXT record, or it will be a CNAME pointing to the key in your provider’s DNS.
Do I need a DKIM record?

What senders are failing DKIM?
DKIM check fails happens when the DKIM authentication checks fail. DKIM signature domain and sender (Header From) domain do not align; DKIM public key record, published in DNS, is incorrect or is not published at all; Sender’s domain DNS zone is unreachable for lookup.
How do I validate DKIM?
You can test DKIM by sending an email to a Gmail account, then opening it in the web app and clicking on the “reply” button, and selecting “show original”. In the original format, if you see “signed by along with your domain name,” then your DKIM signature is valid.
Can I use txt instead of Cname?
CNAME records usually work to verify your domain ownership, but sometimes you may want to use a TXT record instead. Your domain provider doesn’t support CNAME records. Your domain provider supports CNAME records, but you aren’t able to modify them.
How do I set up a DKIM TXT record?
1 Determine which domains are allowed to send outbound mail on its behalf. 2 Create the DKIM public/private keys and the policy record. The ‘public’ key will be used in your public-facing DNS TXT record along with what’s called a policy record. 3 Create TXT records using the DKIM information created from these wizards.
What is the difference between DKIM TXT and SPF TXT?
The DKIM TXT record will begin with “v=DKIM1;” and the SPF TXT record will begin with “v=spf1”. 5. The records are domain specific and will have to be added to the proper zone file for each domain.
How to find the public key of a DKIM signature?
. TXT v=DKIM1; p= s= indicates the selector record name used with the domain to locate the public key in DNS. The value is a name or number created by the sender. s= is included in the DKIM signature. d= indicates the domain used with the selector record (s=) to locate the public key.
What is the difference between I= and T= in the DKIM tag?
v= is the version of the DKIM record. The value must be DKIM1 and be the first tag in the DNS record. t= indicates the domain is testing DKIM or is enforcing a domain match in the signature header between the “i=” and “d=” tags.
