I thought this might fix another problem I am having and changed my port to 26. When I do this I get the following error:

Task 'david@ideadirect.com - Sending' reported error (0x80042109) : 'Outlook is unable to connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).'

Is there anything else I need to do other than change the port to 26?
