It doesn't come from Eudora, so far as I know.  Brent uses Eudora, and 
his messages don't have an Errors-To, and I just fired up an old copy of 
Eudora (not the current version, but less than 6 years old) and it did 
not insert the header either.   My assumption is that it comes from your 
site's MTA.
 From the headers it appears to be something called "ConcentricHost SMTP 
Relay 1.14".  I've never heard of that, and unless there is some 
compelling reason to run a homebrew MTA, you might get more predictable 
behaviour with one of the major products out there.

The list *does* make itself (actually the list-owner address) the SMTP 
envelope address for errors and bounces, for exactly the reasons you 
mention, and because it is an Internet best practice, if not a formal 
standard.  However, we cannot be responsible for a user or site who 
chooses to override that configuration by running a broken MUA or MTA.
