Technologically Postfix will run fine on VPS systems yes. Even if it is silly for companies to block full CIDR ranges from sending email, it does happen a lot. AOL, Comcast, Verizon, MSN, etc... all do it.
Also, having a valid credit card, name and address isn't any indication that the person isn't going to spam. Knowing who a person is by name, and financially isn't the same as knowing their intentions. Also, there is a lot of fraud going on out there. I have seen people send copies of their ID, and credit card and they not be who they are pretending to be.
