Our total mail volume is much lower than others in this thread (and some would say that our volume doesn't even justify an Ironport), but we're thrilled with the results and lack of spam in our inboxes.

I would also note that since installing our Ironport in January, the amount of attempted messages we get has halved. I wonder if this means that spammers "blacklist" us as not worth delivering to anymore or if this is just our good luck.

here is ours for our 2 c150's

But looking back at the same from Jan we have seen a 26% drop in inbound traffic while clean email stays roughly the same.

And that is on one out of two loadbalanced X1050, so the Totals have to be doubled to show the actual numbers...

Last 30 days on the secondary MX, which is one X1000, show:

I just love looking at this sort of thing, and am blown away at how many emails are stopped at the gateway. I do a quick quiz with some of our users and aske them to guess the percentage of emails that are allowed through. They usually guess anywhere betweem 20%-60% of emails are allowed through. You should see their faces when I say it is alway below 1% of all emails.
