Craig,
I've added this to the transport map on the mailrelay servers.
One issue - it appears that beagle.ci.uchicago.edu is part of a CNAME chain:
beagle.ci.uchicago.edu canonical name = www.ci.uchicago.edu. www.ci.uchicago.edu canonical name = pokey.ci.uchicago.edu.
There does not seem to be an MX record for pokey.ci.uchicago.edu: *** Can't find pokey.ci.uchicago.edu: No answer
An MX record cannot point to a CNAME, so you may need to put in an MX record for pokey, or rely on A & CNAME records to work. I'll be available if you'd like to do some testing, or you can just telnet to port 25 on mailgateway.anl.gov and do some manual SMTP.
Brian

Right now the Argonne servers are set up to pass mail that's sent to lists.ci.uchicago.edu through to shadow-mx00.uchicago.edu. Can you do likewise for beagle.ci.uchicago.edu? (At some point soon, we'll want this for ci.uchicago.edu as well.)
