Yes, I'm currently at 400k to 500k a day but only 30% of my accounts use
Spamassassin. I expect the sales depart to push AV very hard. (I would like
to see it on all accounts by default just to protect my own network).

I'm also pondering the concern that another network could increase my
message rate without warning. We saw that already when other local ISPs
had infected clients, with our clients names in thier addressbooks.

A million messages a day suddenly doesn't seem that far away.
