Michal Čihař - More ham than spam?

I just wondered, whether it is possible to receive more ham than spam emails. After 12 hours server outage, I can say that it is possible. However it takes only one hour and then spam again wins. At least it is good that spam bots are still not clever enough to retry sendins, they simply drop everything what could not be delivered. I only hope that none regullar mail server does it also, otherwise I'd lost that message.
