Does your ISP use it to publish SMTP on the Exchange Server? Or are you directly connecting to the SMTP server from behind ISA via the firewall client? Is it always the same 2 Meg file or different ones you have tried? How many clients have you tried it on? Is it the fw client or SNAT? What kind of connection is in use? Can you give us any more information? I have done it many different ways, even Client-to-ISA-to-ISA-to-Exchange and visa-versa with no problems. Details would help!
