"Spamooborona 1024" software by Yandex allows to filter up to 1024

good messages per day for any mailhost. It is to note: 1024 - it is
not the total amount of messages scanned but the only good ones,
which aren't considered as spam. Once 1024 good messages get passed
through the filter, the rest of mail traffic will be passed without
considering spam or ham until the end of the day.

The patch allows use of "Spamooborona 1024" with Exim by using
Local_scan()'s functionality provided by Yandex LLC.
