Microsoft Vista Mail 6 - Alternate Port - Setup Guide
Important Points
- First you need to make sure the email address(es) you will be sending from have been authorised for your account in our Control Panel .
- These instructions assume your email account has already been setup and is collecting email correctly.
- Take a note of any settings you change.
- Only change the items specified - you should not need to change either your email address, POP3 server, POP3 username / password.
- These instructions are only for Vista Mail 6.x - for other email programs please see How To Setup AuthSMTP or contact us.
- We have instructions for both default SMTP port and alternate SMTP port configurations -alternate port is generally used if your ISP blocks the normal port 25 SMTP access (as many do these days!).
