Dear Peter,=0D=0A          Hi!=0D=0AI have gone through ur problem.It's ver
y clear that u don't have the conceot of mail servers and how do they work.
=0D=0A=0D=0AThe best way is to refer to login to any mail server provider l
ike http://www.ntl.com,http://www.scotnet.co.uk and refer to the step by st
ep instruction of how to register with the mail server in ur system.To send
 a mail through client s/w like outlook express we need to have a mail serv
er ie a server which will send mail to the desired location on our behalf.B
ut for that u should be registerd with that mail server which costs few =A3
/$/RS so if you have registerd with that service then in the configuration 
for ur outlook u need to enter the name of the mailserver.There are two mai
l servers out going and incoming mail server.Outgoing mail server uses smtp
 protocol and the incoming mail server  uses pop protocol.=0D=0AIf u r regi
stered with the service u have access to both these servers.But while cofig
uring ur account in the outlook under tool menu u need to enter ur the desi
red name by which u should be remebered by ur client and then after clickin
g in the server tab enter the incoming mail server and outgoing mail server
 name as supplied by the registering comapany.generally the name pattern is
 like this =0D=0AOutgoing mail server: smtp.ntlworld.com for ntlworld subsc
ribers=0D=0A=0D=0AIncoming mail server: pop.ntlworld.com for ntlworld subsc
ribers=0D=0A=0D=0ANormall incoming mail server name starts with pop and the
 outgoing mail server name starts with mail or smtp=0D=0Aso its this outgoi
ng mail server is to be entered while sending mails using sun.net.smtp.smtp
