It's used to detect mail forwarding loops but it's not mandatory.
FWIW, the RFC 2076 has a list of common message headers with comments, 
and a more useful updated version is also available here:

There's really no method that would work for all mail servers and 
configurations. The bottom line is that it's up to the users to come up 
with filters that match whatever field their servers appear to add, if 
any!
