Hi,

This is my configurations of the greyscanner:

$SCAN_INTERVAL = 600;
$DNS_SOCK_MAX=50;
$SUSPECT_TUPLES = 6;
$MAX_DOMAINS = 8;
$MAX_SENDERS_RATIO = 0.85;

My idea was to be a bit more conservative than
the default configuration. Is there any inconsistency
in the above set of parameters?

Regards,

Jose
