Thanks for the quick reply- You have got to be one of the fastest on the net
:)

ok- I fixed the small problems (the secondary server will go up temporarly
after the new year). I didn't quite understand the following:

What is @server and how do I use it, and I'm not sure what you mean by two
mx records. Do I not need to have postal.higherpowered.com point to the
mail server address in every record?

I'm not sure I follow- I thought every dns record needed a reverse file.
The main machine(web server) here is www.higherpowered.com, along with the
name server taoist.higherpowered.com and the mail server
postal.higherpowered.com

the next went over my head, but I'll send it off to my isp and assume they
understand :)
