But why would I want another Imail server to know that it is connecting to my Imail server?
Since all SMTP traffic is suppose to follow the same RFC and standards, what does it matter as to whether or not it knows it is talking to another Imail server? Plus, isn't that giving out another piece of information that a malicious person could use in some convoluted way? The more you know about what you are connecting to, the more you can know about its vulnerabilities. So your statement, "the X1 code lets other IMail applications know that they are connected to an IMail service" means nothing too me, in fact I actually view it as a slight security risk.

I do not have the answer to your "why we don't change it" question. Nor is it my decision to make or to influence. As the KB article says, the X1 code (in the welcome message from IMail's services) lets other IMail applications know that they are connected to an IMail service.
