Exchange 2003 Server will not allow Internal Servers to Relay

i am having issues with my exchange server allowing mail to relay through it. I have everything setup correctly and just noticed that i can't telnet to port 25 from any of the Allowed ip addresses i have in the print screen. This was working at one point and looks to me like it just stopped in the past week or two. I am still able to send regular exchange emails internal/external any ideas.

So if you look at the image i am on the server 172.31.9.5 and i try telnet 172.31.1.202 25 it doesn't work

172.31.1.202 = Exchange 2003 Server???

no new firewall or AV

this is very odd

from 172.31.1.224 and 172.31.1.40 I can telnet

but from 172.31.1.200 I can't telnet

what could this be????
