Question about this list

[kwhiskerz]

I made a posting to this list yesterday, sending the mail only to 
fedora-list at redhat.com.

After a few hours, I received the following mail:

Delivery Status Notification (Delay)
From: postmaster at bcilabs.org
This is an automatically generated Delivery Status Notification.
THIS IS A WARNING MESSAGE ONLY.
YOU DO NOT NEED TO RESEND YOUR MESSAGE.
Delivery to the following recipients has been delayed.
Redhat at bcilabs.org

I never sent anything to bcilabs.org. What is this? Spam?
