stupid web question

[VB]

Hi, 


 I am getting ready to make my e-smith webmail server visible/accessible from
the Internet.  I have purchased a domain name from Verisign.  But I do not
have a DNS server.  Verisign requires that I give them the names of two
DNS servers. I don't understand why ***I*** need a domain server.  I
understand why ***you*** need one, so that ***you*** can translate
domain name to ip.  But why do I need one at all?

SO I need to get two DNS servers; since I already have my own particular 
domain name, what should I do?  I don't have any extra computers 
laying around to set up bind.

Is there anything else I need to do to get "mydomainname.com" to work; I 
mean is there anything else I need to do to get myself visible, accessible
from the Internet, or anthing else I need to do to keep Verisign happy? (I 
realize these questions are not well-worded, sorry.)

Thanks 

Eric
