what are ur out outgoing mail settings?
your smtp server will be any of your domains that you have. you can also just use server1.t35.net. this is because all of the addresses point to the same server/ip, or at least unless you have a dedicated ip like me.
ur username is the full email address that you are trying to set up.
like if i set up bob @ me.com
my username would be
bob@me.comand my server would be me.com, mail.me.com, or simply server1.t35.net .
if you are confused by all this, i know that you alway have the option of setting up ur email in outlook or outlook express in c-panel. but you don't need to import the registry settings.
