Thanks for your reply, Mark. Because we're changing architectures  
(SPARC to Linux) and MTAs (postfix to Sendmail), we don't want to  
upgrade the existing 2.0.12 installation. So, I've been building a  
2.1.9 installation for the new Linux box and trying to get everything  
squared away before we change. There's a lot of lists & a lot of  
mail, so we want to do it once and do it right!

Thanks again for helping me apply band-aids to my current situation.
