SMTP Block List

if one person sends an email out but CC's 100 people, Does that count as 100 transactions or does it count as 1?

It depends on if their email program is creating a new email connection for each individual recipient. Most of the time I'd expect it to be 1 smtp connection not 100. But sometimes other things get in the way, for example if it's a user emailing through their own mail server that's smart hosting through the relays the 1 email sent could be turned into 100 individual emails (and smtp connections) before it reaches an smtp block list.
