What do you think their mail router should do? If uhnix1.uh.edu cares enough, and is capable of it, they should act as though they were an MX for sugar.hackercorp.com. The risk they take in doing that is that hackercorp.com might unilaterally start MX'ing themselves to uhnix1.uh.edu without asking for permission or paying for any of the costs, and people might get upset. --Ed Edward Vielmetti, U of Michigan math dept
