Hi David, It's my understanding that most of the larger DMARC report generators will produce reports every 24 hours. This is simply due to kicking off the giant machines once a day to process and render *all* DMARC reports for everyone. FWIW, this is the first I've heard of someone asking for a reporting interval greater than a day. Longer intervals would cause report generators to have to hold on to data for that much longer, costing storage. In all other discussions I've been involved in, people have expressed a desire for shorter intervals.. the idea being that quicker feedback can cause quicker insight into any operational problems. =- Tim
