it is first sent to the ops@wm.org address (without "list"), then forwarded via the alias that we did not expect anyone to use (-> T123581#1934528) to ops@lists and does not get accepted there because the sender address is not a list member
the content looks like this:
```
Puppet is failing to run on the "testlabs-puppet-is-broken-here-on-purpose" instance in the Wikimedia Labs
project "testlabs"
Working puppet runs are needed to maintain instance security and logins.
As long as puppet continues to fail, this system is in danger of becoming
unreachable.
You are receiving this email because you are listed as an administrator
for the project that contains this instance. Please take steps to repair
this instance or contact a Labs admin for assistance.
