Actually, I am wrong here. This is happening on your machine because you are
using telnet on OS X Leopard:

Try telnet from a FreeBSD (or any other) machine, and you will get:
# telnet my.mywebsite.com 25
Trying 208.87.33.150...
telnet: connect to address 208.87.33.150: Connection refused
telnet: Unable to connect to remote host
