[exim] Notification of ratelimits being exceeded?

Hi

We're running rate-limiting based on sender address, which has been very effective in reducing the consequences of compromised accounts. Until now, I've been relying on some code on a server that's archiving Exim logs to recognise the blocking message, and email us once per sender, but it's not very reliable. Really I'd like to get Exim to send a notification when someone crosses the threshold for the first time in, say, a 24-hour period, but I can't see a way to do it. The rate-limiting's via an ACL, and I don't have Perl embedded, and don't really have the memory to do so. Anyone got any ideas?

Thanks
