it is a series of options
from ssmtps "sendmail" manpage
Most sendmail options are irrelevent to sSMTP. Those marked ``ignored''
or ``default'' have no effect on mail transfer. Those marked ``unsup-
ported'' are fatal errors. Those marked ``simulated'' are not errors,
but the result is for the program to exit with an informative message.
A sort of fatal non-error.
