Thank you for that tip! I can see in the ratelimit db quite a few hosts
which have reached the 5/24h limit. But strangely in the Exim log I
can't see the appropriate reject messages - although I can see reject
messages for various other ACL's I've set up. Searching by the offending
IP addresses in the logs, I can see them retrying over and over again -
and yet my initial connect ACL never seems to kick in and deny the
connection. I can't really think of a reason for this.
