Is port 25 open or closed in VPS?

Port 25 is used for SMTP (Simple Mail Transfer Protocol) traffic. It is used for communication between email servers. However, port 25 is closed in VPS services due to the risks it poses. One example of these risks is that bulk emails can be sent using port 25. This can result in the sent emails being flagged as spam and the server’s IP address being blacklisted.
