Check out this site:

It doesn't search CloudMark though and CloudMark has many huge clients. Shaw and Telus use CloudMark as their spam filter. |
Is there a way to check if we are on the cloudmark list?
If it was blacklisted there though, and that meant that everyone using Shaw and Telus couldn't send to us, that would mean a whole lot more people couldn't send to us.
