There is a sample script for deleting old spamdyke graylist files in
the spamdyke FAQ. It works on Linux -- you may need to adjust it
slightly if you're using a different OS.
As for deleting folders for nonexistent users... I'm open to
suggestions. I want to eventually extend spamdyke to reject email to
invalid addresses but I have a problem. How can you tell if an
address is invalid? I haven't studied this question closely yet, so I
don't have a good answer.
You could start your studies by analyzing this patch:

More generally i think it's not a job of spamdyke to understand HOW
create the valid address list, it's job is only to consult a list and
deny or allow accordingly.
For example in the link i provide to you there is a script which
generates a list of email by simply grepping stuff on vpopmail dirs .
Once spamdyke has determined if an address is not valid, it must return
an smtp error code to the connecting client, telling him something like
"no such user here" or something like that .
I think you could create the list as a dir structure like the ones for
greylist of blacklist .
An ascii file is not so fast for a large userbase .
This is my 2 cents
Have fun,
Davide
