The problem with this is knowing when to check a quota and what the
value of the quota is. Also, at RCPT time, you can't check the real size
of the message, only the size that was given (maybe) in the MAIL
command.
The following item is already on the Exim 4 wish list:

(3) 01-Jan-02 U Test for over-quota at SMTP time
This is a hard one, because the only way to test for over quota is to try to
deliver a message, certainly if system quotas are being used. And also, the
only available size at RCPT time is the SIZE option, though of course the test
could be run at DATA time. I think maybe we leave this one to an external
program, and require people to use ${run} to access the data. Let someone else
figure out how to extract the current mailbox size!
