Summary

Ran read-only dependency checks for legacy addresses paul@kylawoffice.com and jeremy@demandsam.com before deciding whether to reject, forward, alias, or archive.

Findings

• paul@kylawoffice.com is an active classic distribution list, not a user mailbox.
• jeremy@demandsam.com is an active classic distribution list, not a user mailbox.
• Both are visible in address lists and allow external senders.
• Both route to the same three recipients:
  • Janelle@kylawoffice.com
  • Hatfield@kylawoffice.com
  • jhubbard@demandsam.com
• Direct 10-day message trace showed no direct trace rows, but that is not conclusive for distribution lists because delivery may appear under expanded recipients.
• Targeted member-mailbox search found current messages addressed to both legacy addresses.

Examples From Mailbox Search

• jeremy@demandsam.com: current vendor/newsletter style messages, including Zywave, Trust Mineral, and legal/compliance marketing messages.
• paul@kylawoffice.com: current messages including calendar/birthday response, Churchill Downs, Zoom, catering, TriNet, and RxDC/HR-style reminders.
