This is news to me. :-) Could you give me an example of a worm which
sends itself in this fashion? Or possibly send me a sample?

These features will not be added to Anomy itself, mostly because the
functionality is already there:
- If you are using Anomy with an antivirus scanner (which is
recommended) then most such scanners will scan the contents of
- You could quite easily create your own shell-script "scanner" and
plug into the Anomy rulesets. Such a shell script would simply
do "unzip -l" and grep the output for file names such as
"blah.com" or "blah.exe". If such a filename is detected the
scanner would return an exit code which Anomy had been configured
to interpret as "infected" and treat accordingly (e.g. by
defanging the attachment or quranatining it).
