We experienced exactly no decrease with the McColo shut down a few weeks back, even though we receive 2M+ messages per day. It's interesting that each service provider's spam populations are as different as they are. Some experienced gigantic decreases, others didn't. And it's not like we have just one domain. I know MessageLabs examines spam rates per industry type.

McColo hosted the command and control servers for spam botnets and didn't originate spam directly, at least primarily, according to my understanding.

Hello,
Since McColo closed, we noticed the spam was far more intensive than before.
However, it seems the amount of spam is similar than than before.
Do you feel the same ?
Many thanks, RO
It would seem that the sources of SPAM have merely moved since McColo was shut down and it's going to take some time for everyone's blackhole routes and RBL's to catch up. I have personally noticed a higher delivered spam content in my own email accounts.
