What you are experiencing is that you have two accounts sharing the same SMTP server. You can easily fix this by changing the documentation so it is more visible. - Click to 'account settings. - scroll down left side to 'Outgoing Servers' - on that page you will see all of your SMTP servers - To help fix your problem, edit each one's DESCRIPTION field to have the appropriate email account. This is just for documentation. - NOW, click the account name in the 'account settings' pane and look at bottom row of right side of screen where it links to outgoing SMTPserver. If you see the email address of the other account, you have that account pointing to the wrong server. Click the dropdown menu and select the appropriate server.
