Some ISPs, including DCAnet, AT&T WorldNet, MindSpring, MSN, Prodigy Internet, Sprynet, EarthLink, and NetZero, require you to send all outgoing messages through their mail servers.

In these cases when you try to send a message, you'll see an error similar to the following:

The connection to the server has failed. Account: 'mail.yourdomain.com',
Server: 'mail.yourdomain.com', Protocol: SMTP, Port: 25, Secure(SSL): No,
Socket Error: 10060, Error Number: 0x800CCC0E

You'll need to reconfigure your outgoing mail server settings as follows:

1. Launch Outlook Express as usual.
   

2. From the Tools menu, select Accounts.
   

3. Select the Mail tab.
   

4. Launch Outlook Express as usual.
   

5. Select the server to your account and click the Properties button.
   

6. Select the Servers tab.
   

7. Change the Outgoing mail (SMTP) setting to the one required by your ISP:
   

8. If you're using DCAnet, enter postoffice.dca.net
   

9. If you're using AT&T WorldNet, enter mailhost.worldnet.att.net
   

10. If you're using MindSpring, enter smtp.mindspring.com
    

11. If you're using Microsoft's MSN, enter smtp.email.msn.com
    

12. If you're using Prodigy Internet, enter smtp.prodigy.net
    

13. If you're using Sprynet, enter smtp.sprynet.com
    

14. If you're using EarthLink, enter mail.earthlink.net
    

15. If you're using NetZero, enter smtp.netzero.net
    

16. If you're using AltaVista Free Access, enter email.1stup.com
    

17. If you're using another ISP, contact your ISP for the correct setting for their outgoing (or "SMTP") mail server.
    
    

18. Click OK to close the Properties window and then Close to close the Internet Accounts window.
    

19. Close Outlook Express and then restart it.
    

20. You should now be able to send and receive e-mail from your account using AT&T WorldNet, Prodigy Internet, NetZero, or other ISPs.
