554 5.2.3 Rejection errors

554 5.2.3 Rejection errors

I had issues configuring DKIM earlier. I believe the issue has been corrected, but email is still being rejected with a 554 5.2.3 error.

I am no longer seeing errors in the Zoho control panel and external DKIM tests are showing correct now.

Is my account temporarily locked? If so, will this unlock automatically after XX time or does this need to happen by request?
