Yes, well I thought it did until I looked a second time - the entire portion
was commented out with "#" for some reason.  I usually copy/paste from
/etc/aliases.mailman to /etc/aliases once I run genaliases - for some reason
"#" prefixed my paste.

I removed the comments and tried it again - worked a little better... <sigh>
Feeling a little stupid right now...  

Should the aliases get rebuilt automatically when a new list is created or
does genaliases have to be run manually all the time?

Thanks Mark, once again right on the money!
