How to send Mail to another server

[Peter Farrow]

One point:

if you don't already have a virtusertable, you will need to add an entry 
for every other user on the system once you put one in...

If you have a large number of users where the relationship of 
username/email address is a direct mapping, you can create one easily 
with a simple perl script parsing /etc/passwd,
