How to change SMTP ports for common mailing services
Simple Mail Transfer Protocol, otherwise known as SMTP, is an application layer TCP/IP protocol that sends emails between networks. It sets the rules for delivering messages to a mail server, where they can be retrieved by an email client.
Our service blocks traffic over the insecure port 25, however, most email providers allow this port to be changed; here is how to do so on the most common ones:

Changing NordVPN settings
Some settings within the NordVPN app may also interfere with your mailing application. In this case, here is what you can do:
- Disable the Threat Protection Pro™ or Threat Protection feature in the app settings.
- Switch to a different NordVPN server. Your email provider may block access to its email services from known VPN server IP addresses.
- Change the connection protocol to UDP/TCP.
Note: Some email providers might not allow sending outgoing mail through email clients while connected to VPN. In this case, the only way to use mail service with our VPN is to use email through the browser on the mail service page.
