Sending Email from your Email Program You need to set your email program to authenticate when sending mail and change the outgoing port to 587. This does NOT affect webmail use, it's only if you're using your own email software, like Thunderbird, Outlook Express, Eudora or some other email program. First, add your new email address as a new email account in your email program, then follow the instructions below for your particular email program.

In Thunderbird, do this:

1. Click on Tools > Account Settings > Outgoing Server (SMTP).
2. Change the port to 587.
3. Check the box for "Use name and password".
4. Do not check any of the "use secure connection" options.
5. Click OK.

In Outlook Express, do this:

1. Click on Tools > Accounts. Click on your email account and click on Properties, then click on the Servers tab.
2. Under Incoming Mail Server, in the Account Name box, enter your full email address including the domain name.
3. Under the Outgoing Mail Server tab, check the box for My Server Requires Authentication. (Do NOT check the box for Login with Secure Password Authentication, that's a different thing and not necessary.)
4. Under the Advanced tab, for Server Port Numbers, enter 587 in the Outgoing Server box.
5. Click OK, then click Close.

If you're using newer versions of Outlook, v10+ or 2002+, do this:

1. Click on Tools > Email Accounts, then select View or Change Existing Accounts.
2. Click the Change button, then click on the More Settings button.
3. Under the Outgoing Mail Server tab, check the box for My Server Requires Authentication. (Do NOT check the box for Login with Secure Password Authentication, that's a different thing and not necessary.)
4. Under the Advanced tab, for Server Port Numbers, enter 587 in the Outgoing Server box.
5. Click OK, then click Next and then click Finish.

In Eudora, do this:

1. Go to Tools > Personalities and right click on your email address (or <Dominant> if you only have one email address) and click on Properties.
2. In the box for Login Name, enter your full email address including the domain name. If your email program doesn't like that, try using a + (plus) sign instead of the @ sign.
3. Under the box labeled SMTP Server, check the Authentication allowed box and click OK.

If you're using another email program, look wherever you set up your email address pop and smtp info for authenticating and for the smtp server port setting. Also make sure to enter your full email address including the domain name as the user or login name.
