Repeated mails

Hello, I need some advice with a problem (I believe is an easy question but
I couldn't find an answer):

My server logs is "normally" reporting twice almost every time someone is
sending an email:

./mail.log.0:Oct 11 08:58:23 mail postfix/qmgr[5276]: CCC3C1C015: from=<
nakata@example.co.jp>, size=127578, nrcpt=1 (queue active)
./mail.log.0:Oct 11 08:58:36 mail postfix/qmgr[5276]: E88691CCFF: from=<
nakata@example.co.jp>, size=128101, nrcpt=1 (queue active)

Looking more in detail those 2 ids:

It seems to me that "CCC3C1C015" mail was delivered to "hinsyo@example.co.jp"
and "E88691CCFF" was delivered to quarantine and that is why is logged
twice. Is that right?

One of the users (nakata) is reporting that everytime he/she sends an email
to anyone (for example, hinsyo), they get several copies of the same mail at
once.

The spam-assassin filter is still on testing period so some messages are
marked as SPAM only but are not blocked. Could that be the reason of
duplicated emails?

Thank you in advance.
