If the SysAdmin is worth his weight, then he 
should have an admin at his_domain.com address (or 
postmaster account) that allows email from 
anyone, black hole list or not.

Before I ditched using RBL's all together, this 
was how we had our system set up. RBL's became 
such a hassle and some really prominant ones 
disappeared that I was looking for an alternative 
(not to mention that I was having more and more 
of our clients ending up on them, and more and 
more spam was getting through, go figure...!)

I since have moved to using a 
MailScanner/MailWatch/ClamAV/SpamAssassin 
solution with ActiveSpamKiller (ASK) along with 
Sendmail, and what a difference it has made. Spam 
went to 0% overnight, with no false positives or 
false negatives so far. What is more, is that 
with ASK, my users take care of their own 
white/black listing themselves via email. I have 
not had to intervene yet! And I feel that our 
Windows workstations are more secure if not 
immune from Viri.
