Linux mail fine, Windows not so.

Hi,
After setting up my mail server ok on a seperate RH9 box, I decided to
test Outlook and Outlook Express on my main machine's XP partition.
Connecting to ipop3 was no problem, but when I tried to send a mail
through the mail servers' SMTP port, I continually got 'Relaying Denied'.
(I must add that I have two boxes on my 'network', the mail server is
total RH9, and my main machine is dual boot between RH9 and XP. A
Linksys router connects them up to a cable modem.)
I managed to get mail sent from Outlook and OE by updating the access.db
on my mail server with the address of the router, telling it to relay
for this device. I did this after checking my mail logs on the server,
and finding many references to my router.
I have a feeling that this is a bit of a security risk, and I was
wondering if anyone could confirm or deny this for me.
By telling Sendmail to RELAY all mail from my router (192.168.1.1),
would I be effectively setting myself up with an open relay ?
I don't have to do this in Linux. I simply have the default entries,
with one domain I dislike blocked. It works perfectly.
I tried renaming the computer in Windows XP to the same hostname I use
for Linux, but it didn't work. I couldn't do the linux 'hostname.domain
hostname' entry in Windows, and when I tried to define my domain name in
'domain name' in the Windows network config window, I was informed that
'no domain controller was found'. I presume this refers to a Windows
server with Active Directory or something, that needs to be running on
my network for it to use the domain name I use in Linux.
To recap, Linux doesn't need a router-relay entry in access.db, but
Windows does. Anyone have more of a clue than me ? (easily achieved)
Thanks for your time.
