Has anyone played with using the filtering capabilities of e2k to filter
out domain names and anonymous messages? A quick stab at it caused
messages to stack up in the directory lookup queue

If there was a way that we could set up our Exchange to tell the
difference between spoofed messages and non-spoofed ones then we could
all avoid this problem. After all, I can't tell you how many users I
have that are getting NDRs for messages that they never sent (Kletz just

Well, technically one could use you as a relay by sending a mail message to
a valid mail recipient on your mail system with a valid return address on
another domain (to receive the NDR). It's a lame and inefficient way to spam
though and not widely used as there are so many more efficient ways to
