Yeah, I'm getting the same thing, but not the strings. I'm getting bursts of
emails (all generally from the same domain). Never more than an hour time
span, usually about 30-40 emails. I get two emails to every recipient, both
with attachments containing Klez and Exploit-MIME.gen.b, usually comes with
a web page as one of the attachments. The interesting thing is that the
emails are attaching our users' names to the external domain.

It's a dictionary style spam attack. They seem to be on the rise. I get this
about every other day. Sometime hundreds in the just 1 or 2 minutes.

Within the last week I have suddenly started receiving many emails to
nonexistent accounts, the bulk of which are long numeric strings as seen
below
---------------------------------
The following recipients did not receive the attached mail. Reasons are
listed with each recipient:

<[EMAIL PROTECTED]>
[EMAIL PROTECTED]
        MSEXCH:IMS:Creative Computing, Inc.:CREATCOMP:CHALLENGER 0
(000C05A6) Unknown Recipient

The message that caused this notification was:
---------------------------------

I have my exchange set up to notify my on NDR's which is does so I can
capture any legitimate emails that may have been addressed incorrectly (e.g.
[EMAIL PROTECTED] vs. [EMAIL PROTECTED]). 

The actual messages are spam but I don't see the purpose for the sender to
send it to a bogus address, as there is little chance that this would be a
legitimate email address. Am I missing something?

Thanks
