Sounds like you haven't correctly configured the outgoing (SMTP) server in Outlook Express, as there is no such server as 'smtp'. Are you able to send emails to other recipients OK? If not then log in to the comcast website where you will find help on server settings in Outlook Express and other email clients. Or maybe another comcast user can tell you the correct server name, usually in the form 'smtp.<isp name>.net
