This is left up to your implementation.  Through FYI, you can in fact
retrieve messages you *sent* from the MessageStore

Messages that you have sent are stored automatically in a MessageStore by
the QF Session layer in case your counterparty requests a resend request
from you.  This is necessary because FIX protocol guarantees delivery of
messages, in the correct sequence.  You can disable this FIX behavior with
settings like PersistMessages=N and ResetOnLogon=Y.  This is really only
recommended for market data sessions, i.e. where resend requests are not
desirable.
