Do you have DNS Queries open on your ISA server?, I am not really an ISA expert but if you can telnet to my mail server from outside of your ISA server and not from inside your ISA server, then it's a name resolution issue, try this from your Exchange server: telnet 66.67.177.133 25, if it comes back with the SMTP banner then it's a DNS issue.
