Unable to telnet to port 110

[Raj Atwal]

Yes I can cofirm I can telnet to 110 on my POP3 server (see output in my original email). I can also confirm that netstat -an shows that the port is open waiting for connections. Everything seems like it is there for my POP3 server to allow remote connections to it, but there is something blocking mym connections and I can't for the life od me figure it out.

Raj,
seems an absurd suggesstion but can you confirm whether your pop3 server is 
listening to 
192.168.205.224 (i.e.) your ethernet Ip 
address.....
I mean have you tried
#telnet 192.168.205.224 110
on your POP3 server....?
Thanks,
