sendoff() should indeed return ExitStat instead of -1 if the call
to openmailer() fails.
However, openmailer() will already have stored a proper status
in ExitStat because it calls syserr() before failing, and syserr()
sets ExitStat to EX_OSERR or EX_SOFTWARE.
It makes sense though, to override this by EX_TEMPFAIL in case of
a failing fork().
