James may not be as prone to IP Spoofing as some other servers. One reason is the lack of PIPELINE support. SMTP Protocol has a lot of to and fro communication. Response to spoofed IP address could go to the real IP address, and it may either not be ready to accept responses or this could introduce timing/sequencing issues.
