Set up DKIM

Every DNS provider will be unique to some extent, but the principles that guide this process remain the same. As a result, most of the terminology remains the same as well. This guide may not lead you through every single step with your DNS provider, that is something you will need to know how to do. However, it will show you how this was accomplished for our sample scenario.

You will need to create a DNS record using the tools provided to you by your DNS provider, usually this is whomever you registered your domain with. You will need to consult the documentation for your specific domain registrar.

You need to repeat this process for every domain, as each domain has its own DKIM key.

First, Open a Support Ticket and request a DKIM key from us.

You will receive from us a key, that looks like this:

NOTE: CloudFlare wants you to select that WITHOUT the quotations at the beginning and end. This is important if CloudFlare is your DNS provider.

Example DNS record:


Note the Type is always TXT. The TTL is yours to choose as you see fit, or leave at it’s default. The Host (or Name, or whatever your DNS provider calls it) is “x._domainkey” and the Points to (or ValueTarget, whatever your provider calls it) is where you will paste the entirety of that information that you copied in the previous step.

IT IS VERY IMPORTANT THAT YOU DO NOT MISS EITHER THE DOT “.” OR THE UNDERSCORE “_” IN THE “x._domainkey” RECORD NAME.

Now wait an average of 4-6 hours to ensure DNS propagation, and you should be all set.

Troubleshooting:
If, at this stage, you found that your DNS provider does not support enough characters in a single TXT record to allow you to paste the public DKIM key, here is a tutorial on how to split it into two records: http://hack.limbicmedia.ca/how-to-split-dns-dkim-records-properly/

If your DKIM isn’t working and you notice that your record has a double set of quotation marks at the beginning and end, with extra slashes as well, your DNS provider may require you to remove the quotations at the beginning and end before pasting it in their editor. Correcting this afterward may require 4-6 hours of DNS propagation.
