Your DKIM signature is not valid

[Ookma-Kyi]

I just ran a Spam test on my domain and one of the more critical issues is:

DomainKeys Identified Mail (DKIM) is a method for associating a domain name to an email message, thereby allowing a person, role, or organization to claim some responsibility for the message.

The DKIM signature of your message is:

	v=1;
	a=rsa-sha256;
	c=relaxed/relaxed;
	d=ookma-kyi.tech;
	s=default;
	t=1726690962;
	bh=<retracted>;
	h=From:To:Subject;
	b=<retracted>

Your public key is:

"v=DKIM1;
\"p=<retracted>;
\"
"

Key length: 1024bits

Your DKIM signature is not valid

I literally copied and pasted the text from Active DKIM Selector into CloudFlare default._domainkey txt record.

Any ideas?

Did the entire key copy and fit in the TXT record? Plesk often generates DKIM keys that are longer than normal, and a lot of DNS providers require extra steps to make them fit since they often exceed 255 characters, in which case you have to break them into multiple rows in the same record.

Also, be sure not to turn DKIM off once you configure it unless you want to regenerate the key.

Just tried resubmitting it as there might have been a hard return in between the public key. I'll keep you updated on the issue as progress occurs.

DKIM value looks good now on my side. Let us know how it goes.
