If you have people outside your network addresses trying to send mail through your server, you need to be running a 'mail submission agent' on port 587, as well as the MTA on port 25. If you're not doing this already, you'll have to set it up. Since this access is password protected, and available only to your 'trusted' users, it does -not- need spam-filtering on it. (usually, that is -- you know your customers better than we do :) *AND* the client using Outlook Express needs to configure _it_ to use your server *on*port*587* as the 'outgoing mail server'. This will require entering 'authentication' information (username and password) into Outlook Express.
