This might be because you have an A-Record for lists.cs.illinois.edu 
pointing to 192.17.172.63, which is lists.illinois.edu

host lists.cs.illinois.edu
lists.cs.illinois.edu is an alias for lists.illinois.edu.
lists.illinois.edu has address 192.17.172.63
lists.illinois.edu mail is handled by 5 incoming-relays.illinois.edu.

If you're using sendmail with canonicalization, it would replace the 
name on you.

We have a robot for CS lists, and the name is defined in DNS with an MX 
only.

host cs.lists.rpi.edu
cs.lists.rpi.edu mail is handled by 20 mail.rpi.edu.
