What should I do if my ISP blocks port 25?How To: Email Configuration
If you get an error that states "connection refused" then your ISP may be blocking the default port number for your outgoing mail server. If your ISP happens to block the default port number (port 25), you can use port 26 as an alternative port number.

If you are using an email program like Outlook, you can change your port number for your outgoing mail server by clicking on "Advanced settings" or "More Settings" from the "Advanced Settings" tab and changing the port number to 26 in the box that states "Outgoing server (SMTP)". Then click "OK" to save the change.

However, if you are travelling or find that your ISP has also blocked the use of port 26, you can also use submission port 587.
