We're migrating from Exchange 5.5 to 2003. For years we've used Process Software's PMDF as our SMTP mail gateway. Our Microsoft Rep has been pushing us to move off of PMDF and use Exchange 2003's smtp mail gateway. They tell us Exchange can handle the email load we have along with the spoofed messages and bad addresses. In order for me to make a go/no go decision I'd like to hear from this forum on issues, concerns, successes you've had using Exchange 2003 as your smtp gateway.
