There are quite a few reasons that mail can be marked as spam besides an 
RBL.  It is quite possible that an RBL is not the reason that your users 
are having trouble.  Absence of a reverse DNS definition for your 
server's IP address is one that will almost guarantee that mail sent 
from your server will be tagged or rejected.

These lists are not likely to be used by many sites.  If your IP address 
is listed on an RBL that no one uses, will it prevent the delivery of 
any mail?

A significant RBL will publish the process that is to be used for list 
removal.

Being listed by Spamhaus, Spamcop, or SORBS for example, would be much 
more of a problem than being listed by the ones you have shown.  You 
need to do some work and contact the sites that have received your mail 
to find out the exact reasons why it has been marked as spam.
