RoadRunner.com (rr.com) is an ISP with several markets across the
country.  We have had so many complaints about their clients spamming
that we have had to start blocking certain IP addresses.  A bounce may
be an indication that they are starting to require their ISP customers
to use their outgoing email server much like Prodigy.net, Earthlink.net,
and MSN.com.  This requirement is a way for them to determine who is
actually spamming and cancel their service.

Have your client, set the outgoing e-mail server to RR.com settings. 
That is, if they are using RR.com to access the Internet.  If not, then
rr.com may be blocking their emails????
