With the above configuration, only the smtp ACLS statement works (I could telnet to port 25), but the rest of the port redirection statement don't work. If i removed the smtp statement, then all of the port redirection work (i could telnet to ports 110 and 80). Anyone knows why that is the case? Thanks.
