You need to check user's quota on routing stage, not transport.
I have wrote perl script for my setup that checks existence of maildirsize file
and counting quota value for mailbox on smtp-processing stage, thus if user
overquota exim's router will return error and you can treat it as 4xx or 5xx
response.
Here is example of exim router:
quota_check:
driver = redirect
domains = +local_domains
allow_defer
allow_fail
condition = ${if \
eq{${perl{check_quota}{$local_part}{$domain}}} {no}\
}
data = :fail: Account is under quota //5xx error
#data = :defer: Account is under quota //4xx error
