Pending Confirmation Request
From Harmony Lists KB
Confirmation requests can be viewed via the Confirmation tab of the Moderation Queue panel. This tab displays both subscription confirmation requests and verification of email requests.
A confirmation request is sent out when someone signs up for a Mailman List and the list subscription settings is set to confirm. If someone signs up for Mailman List for the first time using Affinity, then a verification email is sent out regardless of the list subscription settings. This verification task is part of Mailman 3 core and it cannot be avoided. A verification request will also be displayed in the Confirmation tab. It will look exactly like a confirmation request and that cannot be helped.
