I've started getting spam in the form:

From: Bill(_at_)syth(_dot_)serveftp(_dot_)net

Now, syth.serveftp.net is one of my dyndns domains and I know that 
there is no valid user on my machine named "Bill."  there are only 
about 20 user accounts on this machine.  I could, I suppose do a ls 
/Users > local.usernames and then check on that file, but this would 
mean manually updating the local.usernames file.

So, how can I get procmail to check tif the claimed from is valid?
