I am caching DNS entries locally for the sake of performance.  I do 
however have my ISP's DNS servers listed as well in case the local 
machine does not have a name cached.  RBL checks are not occurring at 
the MTA (sendmail) level.  The only other rules I have added myself 
would be the and one other german ruleset to stop 
german spam, that's all.*

*One other thing I have noticed in the log is the following message:  
"stat=timeout waiting for input during message collect".  I am going to 
see what I can find out about that error.  If anyone has any input on 
that I would appreciate it.
