I meant what variable do we assign the value to? Like there is "quota" to
specify the upper limit, but there's no separate variable to store the
current disk space used that exim would then use instead of computing the
used space itself internally.

I guess you could do some trickery and rather than using the "quota"
variable to hold the users actual quota, use it to call a program to compute
the used disk space and compare against their actual quota, and if they are
over their quota, report a number less than the incoming message thus having
Exim think they're over their quota and reject the message - BUT Exim would
still go out and do it's own FS check to find out how much space is
currently used would it not?
