But Erik:  Will seismo's sendmail.cf automatically convert the address
to the right of seismo to an arpa-style address just because the '@' is
there?  Does that mean if seismo's ARPAnet service is disabled the
message will lose?  (I hope sendmail.cf has info to do routing in the
presence of the higher-precedenced-network failure, but I haven't looked
at it yet to know.)

Sample message (and Erik's solution) included:

>> floyd!harpo!seismo!hao!hplabs!sri-unix!reiher@ucla-cs.arpa
