This is wired output but as Era stated I could believe it:

From Unix box:

11> telnet nyustern-.collegemailer.com 80
telnet: nyustern-.collegemailer.com: Name or service not known
nyustern-.collegemailer.com: Unknown host

12> telnet nyustern.collegemailer.com 80
Trying 209.200.118.155...
Connected to nyustern.collegemailer.com.

From DOS command window:

C:\>telnet nyustern-.collegemailer.com 80


GET / HTTP/1.0
Host: nyustern-.collegemailer.com

HTTP/1.1 302 Object moved
Connection: close

But my issue is how can I resolve this at code level - what I need to do in such a case?
