Your Sympatico server should be shown on the right. Click it, and then click the Edit button. The account settings should be as follows:

Make sure that this outgoing server is assigned to your Sympatico email account. In the Account Settings dialog, click on your Sympatico account in the list on the left side. The Outgoing Server (SMTP) displayed on the right side at the bottom should be the Sympatico SMTP account you configured above.
