Setting up Outlook Express
Page 2.
Step 3. Type the name you want to use in the box i.e. 'myname' then @ then your domain name i.e. replacing 'mydomain.com' with your domain name - For instance we have an e-mail address at UK Trading called support@uktrading.net 
Don't forget that on our webservers you can have any alias in front of the @ so for a domain name of mybusiness.com, you could set up separate accounts like sales@mybusiness.com and orders@mybusiness.com etc.

The following dialog will be displayed.
Step 4. This is where many people get confused! - But it's quite straightforward in reality...

Step 4a. The incoming mail server is almost always POP3 so leave as is.

Step 4b. In the Incoming mail (POP3 or IMAP) server window - Type www. (www dot) then your domain name, i.e. Ours is www.uktrading.net - Yours will be www.yourdomainname.com for instance.

Step 4c. In the Outgoing mail (SMTP) server window - Type either mail.yourISP.com or smtp.yourISP.com depending on which mail transport that your ISP uses. 
Check with your dialup ISP if you are not sure. - The mail account marked (default) is most likely to have your dialup ISP's outgoing mail setting shown in it if your dialup account was set up automatically by their software.

If you are still unsure at this point, just enter any text into the window so that the setup will allow you to continue - You can edit the settings later by clicking on the account you want to edit to highlight it then click the Properties button in Outlook's account manager.

SMTP IS ALSO AVAILABLE FROM YOUR SERVER 
 (But with potential problems)
Your webserver does have SMTP transport directly available, and is www.yourdomainname.com exactly the same as your POP3 server, So, in the Outgoing mail (SMTP) server: entry, you would enter www.yourdomainname.com.

NOTE: Your own SMTP may or may not work for 1 or 2 technical reasons which are briefly described below.
1) For server security SMTP always requires authorization for sending mail - Whenever you dial into the your own ISP's network, you have been identified to their server via your login username & password - You can therefore send mail from your ISP's SMTP server without further authorization.
However, if you attempt to send mail from your own domain's SMTP, you will be rejected because your domain's SMTP server cannot yet identify you and give authorization to send mail.
You must first collect mail from your POP3. Your username & password for your domain will then have been logged by the server and you will have authorization to send mail.
This authorization is open for 15 minutes and then auto cancels, after which, if you want to send mail you'll need to collect again from your POP3.
2) Some dialup ISP's security protocols may inhibit connection to, and sending of mail from another SMTP server.
