Short-circuiting also causes problems if there are multiple domains
involved in the path.  For example, people who try to mail me on JANET
from UUCP or ARPA who follow the addresses I send them can get through.
If they try being clever because they know a shorter path to a gateway,
they're likely not to get through, because I am only authorised to
*receive* mail which comes in via particular gateways.  So, it's an
even more terrible thing to do if several domains are involved.
