Moving large numbers of files

[Tom Smith <tom openadventures org>]

I'm currently dealing with a spam problem from a domain name I recently 
aquired. This company had allowed it to be an open relay for several 
years and, as such, they were getting hit pretty hard spammers.

The problem I'm having is that my mail queue has been approaching 30,000 
emails (or more than 100,000 files). This occasionally causes Sendmail 
to stop accepting incoming connections even when it's still able to send 
mail (using it with MailScanner).

When I try to move the entire directory contents I get "argument list 
too long" and end up having to move the files in "chunks"--that is, I 
specify "mv dfh0* /dest/dir" and increment the last digit until those 
files are moved. I continue this until the queue's cleaned out. This 
allows my server some breathing room until I can address the problem 
with out effecting mail delivery.

My question is this: Is there a way to move this number of files in one 
swoop without having to "chunk" them?
