I received an e-mail in Outlook Express that I have never seen before.
 It was from "System Attendant".  The subject line said 
"[MailServer Notification]To recipient: eManager settings were matched
and action was taken."

The body of the message is copied here:

"**************** eManager Notification *****************

The following message was blocked because it contains sensitive content.
Rule/Policy: Honeywell Block
Action: Quarantine to f:\Program
Files\Trend\SMCF\Quarantine\2004-08-27\19-44-28.27891\DFImessagebody412fc75c6cf3.tmp

Recipient, Content filter has detected a sensitive e-mail."

What is that all about, where did it come from and how do I get rid of
it?  I have never placed a content screen on my computer.

That is a email filter from TrendMicro. Do you work in a company with IT? Ask them?

Looks like someone tried to send you an email that was blocked from
thier email filter system. The system then emailed you to let you
know. You should be able to see who the org email was from.

Really not a big deal, just hit delete!
