When starting up sendmail in the background, redirect stderr to

/dev/null too.  Otherwise, if there is a name resolution problem
the rc files may finish before sendmail forks into a daemon and it
will complain about EBADF on stderr (since init revoked it).
From a discussion between Theo and myself.
