Be somewhat careful about using exotic /usr/sbin/sendmail command lines,
since that binary is almost never actual sendmail on modern systems and
the other common MTAs may not support unusual sendmail flags.  Postfix
handles all the ones you mention (only `-N failure` would do anything),
but it's common for news servers to run tiny stub MTAs like ssmtp or
nullmailer and I don't know how comprehensive their support for sendmail
flags is.
