I've been getting DMARC reports for a new domain I setup saying that the DKIM check is failing. The emails don't get blocked because I haven't set it up to be quarantined or blocked yet.

If I check the status of the DKIM, it says that the key is valid.

Why would DMARC be flagging it as a failure?

I ended up switching my key from 2048-bit to 1024-bit and now it passes. I'm not sure at all why this is, but it works.
