About the same either way. > More seriously what's the claim there: number of connections? Bytes? > Messages? Recipients? (A possibility is that all of them are 90%, but > that seems unlikely to me and would be worh pointing out, too.) Really, it's about the same. People have been collecting stats on this for upwards of a decade. For more details, Google is your friend. > Besides which 90% vs 100% doesn't seem very significant to me. I gather you've never run a large mail system or talked to people who do. The 90% is an average over all sources. Some sources like the IETF's mail system send about 0% spam, some like Tor and botnetted old Wordpress servers send 100%, others are in between. To keep the load manageable, you reject mail from the very spammy sources and use your servers to filter what you accept. There's a reason that every mail system of any size has a Spamhaus subscription. R's, John
