Sendmail 8.13.7 Constant Blacklisting

I have been running Fedora Core with Sendmail 8.13.7 for a few years
now. Currently its function is to scrub all spam and forward to my
internal microsoft exchange server. It does a very good job but at
times I get added to multiple blacklists which prevents my users to
receive and send email. I tested my box for open relays it passed. So
i need some direction on how I get blacklisted. Your feedback is
greatly appreciated.

Here is a Header that was caught by MSRBL

Looks like you haven't stopped it being an open relay. I'd suggest you
re-check, check your access file (probably /etc/mail/access) and if you
find nothing obvious, post your sendmail.mc (NOT sendmail.cf).
