By Friday morning, I was seeing maturity info in tracking logs that looks like this:
Message 7665687 Consolidated Sender Threat Level: Neutral, Threat Category: N/A, Suspected Domain(s) : N/A (other reasons for verdict). Sender Maturity: 30 days (or greater) for domain: mailch.docusign.net
Verify your SDR content rules if you're using them.
An SDR rule set to catch domains with an age <= 30 days or age == 30 days WILL FIRE as if this domain age is exactly 30 days.
