Go to your mail program, and change the outgoing server settings to match the settings below. Also, make sure your mail program is authenticating with the outgoing server using the same information as the incoming server.

This may vary slightly depending on the Email Client you are using such as Outlook, Outlook Express, Apple Mail, Thunderbird, etc.:

1. Make sure that you have your SMTP server set up correctly. The server will be your domain name. You'll also want to confirm that you have it set up to authenticate with your mailbox username and password.
2. The more likely problem is that your ISP (Internet Service Provider) blocks external SMTP servers from being used when you are on their network. Contact your ISP and ask them what SMTP server you should be using.  Alternatively, you can usually get around this block by configuring your outgoing server settings to use custom port 2525 (instead of default port 25).

Your ISP may be blocking port 25 which is becoming more and more common. This is a method imposed to prevent spammers from sending e-mails from their location and making it harder to send spam.
