[cobalt-security] Safe SMTP relaying

["Simon Wilson" <simon@xxxxxxxxxxxxx>]

Hi,
I have a client that uses an msn account to send and receive e-mail.
How do I go about finding out what IP address to put into the SMTP "relay
for the following hosts/domains" box on the admin pages. Is it just
www.msn.com ?
I don't want to get it wrong and get a load of spam being relayed.
Also can anyone point me to a good explanation of readouts from log check so
that I can stop asking here everytime I see something I don't understand.

Thanks
Simon
