Thanks.

I think what I was trying to say before was that I didn't put this document out there to convince anyone of anything. It's there to help people who are already convinced, and are looking for How To Do It, since there is precious little of that in the MTA crowd specifically, and the sysadmin crowd in general. If people aren't already convinced that Exchange is a POS, then my little HOWTO document is not the place to try to convince them. Attempting such makes me look like a kook. ;)

Well, if I were an old UNIX'er, I'd do so. :) I learned on Apples and am employed on Windows. UNIX, I'm still leraning about. So again, thanks for the tip.
