Thanks for this, Bill. I'll try it right away. I had avoided setting up Webmin because of the dire warnings I found somewhere in the documentation about Zimbra needing to be its own standalone server. Mix that with my trying previously on a box that already had Apache running--which failed spectacularly--

and you'll know why I was a little gunshy.
I'll give it a shot. . .I'd like to have the Webmin for SpamAssassin too anyhow.
