I have now configured the sendmail delay_checks feature and it looks like the one I want.  
All test have worked ok and I'm ready to let the users at it.

One of the nice side effects of this is I can see the FROM & TO addresses of any mail 
which gets dropped because of RBLs.  It should make it easier to track down when there 
are problems.

Thanks for the help.

I will take a look at this as well and see if it can give me anything more.  Should be useful 
for the few remaining AOL users out there.
