Granted, but it at least shortens the window. Checking in multiple places 
should shorten this further, no?

All home directories are on AFS.
Users want mail in thier home directories. I want user's mail quotas as 
part of thier overall disk quota. Having a second quota for mail is all 
well and good, until the user recieves a large file (this is a common thing 
in our company) and it takes the whole thing. At least with a single large 
quota of thier home directory they can free up some space and recieve the 
mail in the unlikely event that it bounces. It is unlikely that any user 
will see thier AFS quota full anytime soon. It is perhaps worth noting that 
we have alot more disks dedicated to AFS than to the mail server.
