I've talked to "People" at cisco before about email handling stuff, it takes them a lot of effort to make lists such as 'cust-security-announce' deliver quickly. I've had some experience tweaking large lists as well, it takes a significant amount of effort to deliver to 2k users quickly. Cisco has a lot more than that registered, and I suspect the delivery is a bit more complicated with all the dns/resolver load going after all the possible customer domains they have.
To give you a rough idea (cisco-nsp for example is a list I host and is delivered fairly quickly by most peoples standards..) smtp to cisco-nsp for 2655 recips, completed in 341.639 seconds
Now imagine if instead of 2655 users it was 1-1.5million, that puts it at 53 hours in my rough guestimate. (assuming i know what i'm talking about, and the higher number of 1.5m).
Perhaps Cisco should hire some spammers to consult for them. Those folks certainly don't seem to have a ~7-8 mail/sec limitation. :) -- Richard A Steenbergen <ras@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC)
