In this example, we'll be using Microsoft Outlook, but the settings will be similar whichever email software you use.

1. Open MS Outlook and click Tools/E-mail accounts. Click Add a new e-mail account and click Next>

2. Choose POP3 and click Next>

3. Now we are at the TRICKY page ! Look at the screenshot below. In this example our website is called www.sagan.com and our email address is setup as carl@sagan.com. Carefully check your settings against these example ones>

Notes. Your Incoming mail server (POP3) is mail.yourdomain.com, NOT mail@yourdomain.com

Your Outgoing mail server (SMTP) refers to your internet service provider (ISP) and so for example, in Australia it might be mail.optusnet.com.au
If you don't know this setting, try googling for it or ask your ISP.

Your User Name is your entire email address, not just your name.

4. Finally click the More Settings... button and on the Advanced tab, ensure that Leave a copy of message on the server is NOT ticked.

5. You are now ready to click Test Account Settings... you should get all ticks and then receive the test email.
