[CentOS] ViSpan

I was looking for the old Vispan stuff, and it seems to have disappeared 
from the web. Now I realize it was old, but it did provide some details 
that I liked on my old servers. I've got mailscanner-mrtg running, but 
that only provides a view of what mailscanner sees.

Does anyone know of a good replacement for vispan that might give 
complete stats on what the mail server is doing instead of just what 
MailScanner is doing?

thanks
