Excellent, thanks for the info!  The qmail solution was something I
inherited.  I had the opportunity to rebuild the server (read:
unmaintained rh6.2 got root'd) but really had to keep the existing
data structure with qmail/vpopmail to get the server back online in
any kind of reasonable time.  Hopefully the extra hardware will take
care of this.

Looks like an interesting package, I can probably use it with the load
this servers seeing.

Thank you again!
