Conversation: How to tell if email was sent from inside or outside
exchange
Subject: How to tell if email was sent from inside or outside exchange

Exchange 2003 - Symantec CE for exchange running - all users are either
OWA
or POP3.

We have an outbreak of viruses and all are coming from one address.  Now
I
can just block that address and be done but looking at the message
tracking
logs I can not tell if the message originated outside our system or
inside.
Obviously if it came from inside I want to find the machine and correct
the
issue.

So how can you determine if the message originated inside or outside.
