DKIM Record Lookup

Check if a domain has DKIM configured. DKIM adds a digital signature to emails to prove they're authentic and haven't been tampered with.

Understanding DKIM

DKIM adds a digital signature to your emails. When someone receives your email, their server checks this signature to make sure the email really came from you and wasn't changed.

DKIM parts explained:

Selector: A label that points to your DKIM record
Public Key: The code receivers use to verify your signature
Private Key: Your secret code for signing emails
Key Type: The encryption method (usually RSA)
Key Size: Bigger numbers mean better security (2048+ bits is good)
