Please Note: This is a premium feature. Please contact your account manager to setup.
Please note: A Custom Return-Path domain is a prerequisite, required for DKIM implementation. We can support DKIM on multiple Custom Return Paths. Please see this Custom Return-Path related article.
What is DKIM?
Domain Keys Identified Mail is a method of cryptographically signing emails. It allows the receiving server to verify that the email has not been tampered with in transit and that the sender is who they say they are. It is arguably the most complicated authentication protocol. You use a private key to encrypt the emails you send and the recipient's server uses a public key to decrypt the email.
DKIM can be thought of as a safe and combination. Each email is secured inside a unique safe with a common publicly available combination that can open each of these safes. There are details inside the safe that prove the domain is owned by the sender.
Why is it important?
DKIM can help prevent spammers from forging your domains. Along with SPF records DKIM can improve overall delivery rates by ensuring that recipient servers know you are a legitimate sender.

How to setup DKIM
1. Setup a custom return path
2. Vuture will generate the required Public and Private keys.
3. Your IT team will need to add the public DKIM to the DNS record. Example provided below.
DKIM records
----------------
Record Name: "vx._domainkey.{custom-return-path-subdomain}"
Record Type: CNAME
Record Value: "{custom-return-path-subdomain}.vuturedkim.com"
Record Name: "vx1._domainkey.{custom-return-path-subdomain}"
Record Type: CNAME
Record Value: "{custom-return-path-subdomain}.1.vuturedkim.com"
4. Once you have implemented the public key, we will verify that it is correct.
5. We will then configure DKIM.
6. We will then test DKIM has been setup successfully.
7. We will then inform you that setup is complete.
8. If you wish then you can then carry out your own testing.
