Outlook Express

Some ISP's block SMTP Relay causing outgoing messages to bounce. If you are still experiencing problems with outgoing mail after changing the port settings in the last example you may have to use you ISP's outgoing SMTP mail server settings. Please follow the instructions below.

In the Menu bar click on "Tools" and then "Accounts"

Click the "Mail" tab
Highlight the account name
Click on the "Properties" button

Click on the Servers tab
Change the SMTP Outgoing mail server settings to your current ISP SMTP settings
   (You may have to call your ISP to get the correct SMTP Outgoing mail server settings.)
Make sure “My Server Requires Authentication” is checked
Click "Apply" at the bottom
Click the "Settings" button at the bottom

Make sure "Log on using" is checked
Type in your email name@yourisp.com and password from your local ISP
Click "OK"

Go to the"Advanced" tab
Make sure the Outgoing Server Port setting is set to 25 since you are going to be using your ISP.
Click "OK"

Click "Close" to close the Internet Accounts box

If you are still having problems, reboot your computer and try sending email again.
