This article explains that 2048-bit DKIM public keys often exceed the 255-character limit for a single DNS TXT string (per RFC 1035) and provides a step-by-step guide to correctly split and publish DKIM records so DNS resolvers can reassemble them; it covers manual and automated splitting methods, common errors and fixes, provider-specific instructions (AWS, Google Cloud, Cloudflare, cPanel), verification practices, and recommends a client-side DNS record splitter tool.
