TCP/UDP PORT RESTRICTION

The complete internet security policy is unpublished, but the following items may affect daily use and are listed for your convenience.


  • Outbound TCP port 25 (e-mail via SMTP) is largely prohibited. This is in place to prevent viruses from propagating to the internet. As a workaround, you may try an alternate port such as 587 (assuming the specific SMTP server is available on an alternate port).
