- DKIM records are implemented as text records as well. The record must be created for a subdomain, which has a unique selector for that key, then a period (.), and then a protocol name 'domainkey' and the domain name itself. The type is TXT, and the value includes the type of key, followed by the actual key. Both 1024 bit and 2048 bit keys are.

Add Dkim Key
The first step in setting up DKIM for your business is to generate a private/public key pair. Next, the public component of the key needs to be a TXT record assigned to the domain used as the sender address. Then, the private key is utilized to create a DKIM-Signature for each outbound email.

Generating 1024 bit DKIM key
To generate a DKIM key with openssl, do the following - this will generate you a 1024 bit DKIM key: http://saicategi1978.wikidot.com/blog:20.
Your generated public key will remind something like below:

If you need to supply the public.key in the DNS record as follows, you have to 'convert' it manually to be in one line, i.e.:
In bind/named compatible format, it will look like below TXT record:

Please note that you may want to use a 2048 bit DKIM key - in this case, use the following openssl commands:
However, 2048 bit public DKIM key is too long to fit into one single TXT record - which can be up to 255 characters. Assuming your full public key is as follows:

..you need to split the text field into parts having 255 characters or less:

There are several limitations to 2048 bit DKIM records:
There are several limitations to 2048 bit DKIM records:
- While bind/named supports TXT fields being split into several parts, some DNS hostings may still not support it.

- If the total size of the DNS record is larger than 512 bytes, it will be sent over TCP, not UDP. Some buggy firewalls may not permit DNS packets over TCP.
