What part does what? Does the first part run the scanmail.pl script and 
the second part put the message somewhere? If so, what is the lock file for?

Would this do what I am after:


* ^TO_clamav-db@
|/usr/bin/freshclam


As I said this e-mail address is used for nothing else but receiving 
notices that the database has been updated, I don't need to keep the 
messages.
