Subject: eximconf: log the current rate at which penalised senders are sending
X-Git-Url: https://git.adam-barratt.org.uk/?a=commitdiff_plain;h=d22b9d5e3d4e4a8ac85339b87a66792de597a8c5;p=mirror%2Fdsa-puppet.git

eximconf: log the current rate at which penalised senders are sending

The use of the "strict" modifier ensures that the count is always updated.
The default "leaky" mode stops updating the count once the limit has
been reached.
