[PLUG] "from=<>"

[Billy Dimaculangan]

I found this strange things going on in our server maillog.  upon reviewing
the the daily mail delivery report, if found out that "from=<>"  was
included in top 10 Senders by message count and top 10 Senders by message
size. This "from=<>" also exist in our maillog and sending out mails to
other domain. we are currently running postfix in our mail server.  i'm
wondering if any one can clear things for me regarding this matter. i hope
someone could help me with this one..

TIA
