Port 8025 for Mail, getting around your ISP port 25 block

The land-line Telco's and Cable companies have a habit of blocking SMTP port 25 to mail servers outside of their internal network. If your ISP is blocking port 25, there are several common ports to try, 80, 465, 587, and 8025.

Most mail servers (and control panels) allow for additional port(s).

In Kloxo it's Home (admin) -> Severs -> Server Home (localhost) -> Server Mail Settings.
