Where is DKIM selector for domain?
The easiest way to discover the selector for your domain is to send an email to yourself.
- When you open the email, view the “original message” (some email clients might call this view “raw” or “full headers”) of the email.
- Search the headers for “DKIM-signature” to find the DKIM signature applied to the message.
Is DKIM a TXT or Cname?
DKIM requires the addition of public keys into your DNS zone. 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.
How do I validate a DKIM record?
You can check/validate your DKIM record by using our DKIM record Checker.
- Enter ‘Google’ as the Selector. As an example, we’re using a generated domain key from Google Apps.
- The DKIM record is correctly configured when the DKIM Checker shows ‘This is a valid DKIM key record’.
- If the selector is not valid.
What is a domain selector?
A selector is arbitrary string appended to the domain name, to help identify the DKIM public key. It is part of the DKIM signature, and is inserted into the DKIM-Signature header field. During the validation process, the selector adds an additional name component, allowing for differential DNS query names.
Can I have 2 DKIM records?
Yes, you can have multiple DKIM records, TXT or CNAME-typed, on a single domain.
How many DKIM records can you have?
It’s possible to have more than one DKIM key published in your DNS records. So, the DKIM selector is important for ensuring that your emails can be properly authenticated. The field specifies which DKIM key you’re using, and the field is filled with your domain name.
Why is DomainKeys Identified Mail ( DKIM ) alignment important?
Domain alignment is important for Domain-based Message Authentication, Reporting & Conformance (DMARC) to work properly. Domains out of alignment may cause the DMARC check to fail. DKIM alignment is when your email’s parent domain of the DKIM signing domain matches the Header From domain.
How do you validate a DKIM key record?
The DKIM record is correctly configured when the DKIM Checker shows ‘This is a valid DKIM key record’. After entering the ‘selector’ combined with the associated ‘domain’, the DKIM validation tool will show a full list of all the DKIM results of the specified domain.
What does a DKIM selector do in DKIM?
A DKIM selector is text that is added with the domain to create a unique DNS record used during DKIM. This allows multiple keys to exist under one domain which allows for different signatures to be created by different systems, date ranges, or third party services.
What happens when a DKIM authentication check fails?
DKIM check fails happens when the DKIM authentication checks fail. Here are possible reasons for check failures: 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;
