sequester_orphans.R tried to send an email to a blank email address. This happened on the second sequestration job I ran on 2022-11-02.

WTF? How did we do that on project 9519? I thought we filtered those odd-ball records out.

How should we respond to this? Not sequester? Not email anyone about the sequestration?
