Blank Emails coming from outside our network

Posted on 2011-05-10

Over the past week, we have had an increase of blank emails being delivered to two recipients within our network.

The email send only has this in the From box

From: "" <>

Ive checked the tag info and its not showing who its from and there is no txt in the body of the email.

how would I go about tracing the source or simply just stopping the message from getting into the mailboxes?

The email system is Exchange 2003 and our spam filter are Google App Security.
