b. If your email service does not offer this feature, you can use a DKIM mobile phone number list key generation tool or an online generator to create a DKIM key pair. A popular tool is OpenSSL:
openssl genpkey -algorithm RSA -out private.pem -aes256 -outform PEM
openssl rsa -in private.pem -pubout -out public.pem
These commands will generate a private key (private.pem) and a corresponding public key (public.pem).
2. Configure your email server:
a. Access your email server settings or control panel and look for the DKIM settings section.
b. Upload or copy the private key (private.pem) to your email server's DKIM settings. The way to do this may vary depending on your email server software.
c. Ensure that the private key is kept secure and not exposed to unauthorized persons.
3. Add a DKIM DNS record:
a. Once you have configured your email server with the private key, you need to create a DKIM DNS record. This DNS record will allow receiving email servers to verify the authenticity of your emails.
b. In the DNS management interface (provided by your domain registrar or hosting provider), create a TXT record with a name that follows the DKIM selector format. The DKIM selector is a unique name that you choose that is used in the DKIM signature. It is usually a short, descriptive name, such as “2024″ or “default.”
