BGP & reverse dns

[Steve Suhre]

I have a client who's using BGP on their own network but use our mail 
servers. They're having trouble sending mail because the server here 
can't resolve the IP address back to their network. And if I run the IP 
through DNSStuff.com it returns an infinite loop error. They claim they 
aren't having trouble anywhere else though....

I don't want to turn off reverse lookups, is there anyway to get around 
this? Or a simple fix on their end? I know nothing about BGP routing... 
We're running sendmail, and spammassassin through procmail. The mail 
problem started recently when we upgraded sendmail and added 
spamassassin, but their DNS/BGP problems have been there for a while....
