Some ISPs block the standard outgoing SMTP port for security reasons. As a result, the default port is not accessible for your email client, i.e. Outlook, to send emails. Delphi's servers are setup with an alternate port for sending emails. Modify your email account settings in Outlook or your preferred email client and change the outgoing SMTP port from 25 to 2525.
