Hello folks I can't seem to paste my full DKIM key .txt record in my zone editor, there seem to be a character limit? my DKIM key is about 455 Character long, but CPANEL only allows me to paste up to 255 characters per .txt record? How do i go about this? P.S I have been uisng CPanel for over 10 years with a few installations, this is a new WHM installation and a new cpanel account so not sure if there is some tweaking i need to do on WHM side. Thanks a bunch

  Hey there! If you click "Edit" below the record you'll see an option to break it up into two parts like this screenshot (this is a fake domain, so it's fine that I'm putting these out there): That's normal for a cPanel system, and if you check the record on the command line you'll see this: default._domainkey 14400 IN TXT "v=DKIM1; k=rsa; p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA04a4a/YymB1ROdKjskOnSBT7MqZdzabMb4nniATKG/Epuu9P+fjgIpuQ6bOlPNjxD0eUkCac0LSPv9kud6jIvBd3EXTPjzePndoy123XNcWQZ0aDvUyjw9G4h7bcu/A6+9uKISMmmW9gETxbubcUd6++davo//vc+AiMcUlidzken5f2OT9or/hG1bcpxkyc8" kg6zthzXXEXJMkMVIdsf3XNwgd3QM6SLJiEmxZFJatDJopjCI7VY7msksbXwrF/bMZPnw5NtnMcmaYP4g1jS/QbBwJKUL3IJk8ggo1DG5dRlmCGVCYU13ZBUWzyM1vFKs7EdNFVngCW9R18ZOEV9QIDAQAB\;
  Is there a reason you're trying to paste a record into cPanel instead of letting the software create one for you?

  This isn't a solution; surely breaking up the string leaves room for error? The last system you had didn't require strings to be broken up. It makes no sense why there's a character limit.

  Hello Reado!

  I wanted to offer some clarification here. In v94, the DNS Zone Manager would automatically split TXT records that were entered in the interface behind the scenes after the record was saved. In v96, we introduced multi-part TXT records. While this is great, it seems that this is now the enforced default, and there is no way to add a TXT record in a single, full line if it exceeds 256 characters. We've published an internal case with our development team on this, CPANEL-37236. We've also published an article with additional information on this case here: Why are DKIM TXT records split?
