should beHalten Sie Ihre Klappe.(Petra is female).Haltens seine clappe!
i know this is
waay off topic but:
'sie' is (in this
context) the polite translation of 'you' (in opposite to the informal
translation to 'du') (and 'ihre' is the polite translation of 'your'). even if
the mail came from a 'hans' then you have to write 'Halten Sie ihre
Klappe'.
btw: if you want
to be that rude you could also say 'halt deine klappe' where 'deine' is the
informal translation of 'your'. or just 'schnauze!' where you can omit any form
of adress.
