sendmail: no local mailer

evantd> # sendmail -L sm-mta -bd -q30m -ODaemonPortOptions=Addr=localhost
evantd> 451 4.0.0 No local mailer defined: Bad address
evantd> 554 5.0.0 QueueDirectory (Q) option must be set

/etc/mail/sendmail.cf is a bogus (empty?) file.  One way to fix this is:

cd /etc/mail
mv sendmail.cf sendmail.cf~bogus
make
make restart
