Postfix Log Analyzer

[Manuel]

I have searched around and found a few postfix log analyzer (pflogsumm.pl, awstat, etc) but none provide the format below.

Mon May 17 21:12:52 2010: from=sender@abc.com, to=user@example.com, size=202432
Mon May 17 20:29:18 2010: from=sender2@abc.com, to=user2@example.com, size=3008

Currently I am using sma to produce the above but it's only for sendmail.

I just need a simple log analyzer for me to track emails like above.
Format: Date / Time / Sender / Receiver / Size

Any help would be appreciated.
