Info from CIT's ID Management
Per ID Management's Jerry Shipman (Wednesday, October 12, 2016 4:13 PM):
if cornellEduMailDelivery contains "exchange", mail is going to the exchange mailbox.
if cornellEduMailDelivery contains "cmail", then mail is going to the cmail mailbox, and mailRoutingAddress will also contain the netid@cmail.cornell.edu (this was an expedient decision that was made to solve a technical problem)
if cornellEduMailDelivery contains "maildelivery", then mail is forwarding to the external address(es) listed in a comma-delimited list in mailRoutingAddress
CIT has it written up here: https://confluence.cornell.edu/display/IDM/Attributes
Take care,
Jerry Shipman

Jerry,
This does seem like a much better "fit" to my needs. I just tried it in Windows and my tests got me what I needed, using your search parameters to guide me towards what to try in the tool I tried. I'm sure what I did can be made more elegant, but it does work. 
Thus, no policy statement needs to be crafted in regards to my query. I really don't want access to any FERPA data and the like, of course. Should I forward this email to the ticket, or do you want to share that you got me what I needed?
And thank you! -Oliver.

Subject: mail forwarding information
Hello,
I work in identity management. I guess that someone else has your ticket and I am writing unofficially from the peanut gallery, but...
I'm not sure, but it might be that the information you're looking for is mostly available publicly in the directory.
(...)
Is this all the information you are looking for?

`ldapsearch` is an easy ldap client that is available on mac and linux...one would think that there is an equivalent thing on windows, but I don't know what it is (sorry).
I have also seen guys make ldap calls from coldfusion webpages or what have you. (...)
