As someone who manages a lot of mailing lists, I can tell you that MANY 
people sign up for a list under one address, and then proceed to post 
from another.  Sometimes it's a mistake, but mostly it's just 
carelessness.  A long time ago I would follow up with the person and 
remind them that they were subscribed under a different address, but 
life is way too short; I usually just add that address to the exception 
list of people who aren't subscribed but can post.

I don't run -discuss, but I can see that happening ...

Take a look at the headers for a message on -discuss and see what 
address it was delivered to.

Look for something like this:
