Have you ever recieved spam with fake From and To headers?  There are
headers and there is envelope in message, and latter is not visible to
user.  So, you can user fake address in headers (or do not use headers
at all) and real addresses in envelope (and envelope is visible only
to transport agents, not delivery agents).
