public IPs of CM's mail servers?

One of our clients is about to turn on a spam filter that blocks all incoming emails that don't originate from whitelisted IPs. "ping" says that and are both

Are there any others I should hand over for them to whitelist?

And also, in case our B2B clients ask, what enterprise spam filter companies (Postini, for example) does Campaign Monitor work with to prevent being blacklisted?
