RBL and Exchange 2007

I have a hand full of users that have outside reciepents that bounce back emails sent to them and the error details note 'Message rejected because of RBL policy'

We are running Exchange 2007 and using Vipre (from GFI) for spam filtering. When I run our mail server IP on the blacklist check found at http://www.mxtoolbox.com it comes back clean.

My question is two fold...

(1) Could it be that we are listed someplace else that http://www.mxtoolbox.com does not scan again and if so is there another tool I should be using other than http://www.mxtoolbox.com?

(2) I am under the assumption that I am only relying only on GFI's software for RBL purposes but is it possible that I have it also setup in Exchange? If so how would I check?

I forgot to mention...not sure if it is related but the bounce back all seem to come from folks using Google for their email
