You're partially right. Exim cannot check the total space usage for a
user against their quota. Different file systems store quota information
differently, as do different O/S's. So what happens is that if you set a
MTA quota, it checks to see if in writing the current file the user's
quota would be exceeded. If you're not using a delivery agent (I've
heard some people mention agents like Cyrus or something, but I don't
know for sure), then the best way to do Quota issues is with a File
system Quota. If a FileSystem quota is not an option you need a 3rd
party delivery agent that can read the quota information and return it.
I once heard (I think it was on this list, but don't remember for sure)
of someone who had some kind of hack that allowed quota usage to work
correctly, but it was so long ago I don't recall for sure.
