mailman-loop sending mail to undesirable address
by Macs R We April 8, 2026

I tried posting this twice at the website and it appears to blackholed both times, don’t know whether it’s a new-user moderating thing or what. So apologies if this is a duplicate Hopefully, this is simple. I know nothing about the innards of Mailman -- I've been just using it as a black box for a decade and it's been working fine. Today, in the process of handling a subscriber's non-delivery complaint, I came across this error message in WHM's Mail Delivery Reports: From Address: mailman-loop(a)server.wickenburg.us Sender: Sent Time: Feb 22, 2025, 6:48:18 PM Sender Host: server.wickenburg.us Sender IP: 127.0.0.1 Authentication: unauthorized Spam Score: 0 Recipient: root(a)cloud-ci.unifiedlayer.com Delivered To: Delivery User: Delivery Domain: cloud-ci.unifiedlayer.com Router: reject Transport: **rejected** Out Time: Feb 22, 2025, 6:48:18 PM ID: 1tm16p-00000000BOG-aS00 Delivery Host: server.wickenburg.us Delivery IP: 127.0.0.1 Size: 0 bytes Result: The mail server could not deliver mail to root(a)cloud-ci.unifiedlayer.com. The account or domain may not exist, they may be blacklisted, or missing the proper dns entries. The recipient identified is not anything I ever set up. "unifiedlayer" belongs to my hosting provider, so this may be some sort of default or unset value. I've scoured the Mailman configuration screens for anything resembling this, or any field I should have provided but left blank, and I'm buffaloed. Where is Mailman getting this value from, and how to I change it to something more useful?
