Directing messages to Enkive Mail Archive Server

[අයි. ඩී. චාමින්ද ඉන්ද්‍රජිත්]

Dear All,
I have configured Enkive Mail Archive Server and pointed Messages of 
my mail server to Enkive as follows.

smtp      inet  n       -       n       -       -      smtpd
        -o content_filter=filter:dummy

filter    unix  -       n       n       -       -      pipe
          flags=Rq user=nobody null_sender=
          argv=$ENKIVE_SOCKET_FILTER_HOME/enkive-socket-filter 
localhost 2527 ${sender} ${recipient}

But this will not store mails in user mailboxes in my mail server.

Therefore, I need your help to configure my postfix to send a copy of 
all incoming and outgoing mails of my mail server to Enkive Mail 
Archive Server.

Thanks and Regards
Indrajith
