Hello, I have a 5.5 server that holds only are internet connector and a connector for our fax software. I have two questions. What is the difference between the versions of smtp protocol that 5.5 uses compared to 2003? What will happen if I run the internet mail wizard on the 2003 server? Will it take over both outgoing and incoming? Or since our MX is pointing to the 5.5 only outgoing. Thanks in advance.
