Curious why your #DKIM is failing? A switch to "relaxed" canonicalization vs. "simple" rules may help you get of own way. Under simple canonicalization, even minor line break or extra space can break a signature and impact deliverability. dmarcian.com/dkim-failure... #DMARC #EmailAuthentication

Did you know? The frequency of #DKIM key rotation depends on key length. 1024-bit keys should be rotated more often than 2048-bit keys, as they are easier to break.

The Traditional Email Security Model still assumes trust until something looks suspicious.

That assumption may just be the problem.
