Change the setting that enables you to ask questions that non-psychics

When mail delivered multiple times that will be recorded in your
logs. You need to identify all log entries pertaining to some
sample messages that were delivered more than once.
Avoid virtual alias expansion on both sides of a content filter,
as that can generate a second copy of a forwarding address.
Watch for deliveries that time-out at end of data, Postfix logs
make a fuss about these:
<some problem> sending end of data -- message may be sent more than once
