Is Port 25 (SMTP) Opened on Your Servers?
On our VPS hosting, port 25 is open by default, allowing you to send regular emails from your server. We don’t set strict limits on the number of emails you can send per hour or day.
If you’re using your VPS for email services, it’s important to follow our Acceptable Use Policy (AUP). We may block or limit port 25 if there’s a violation of the terms.
Sending bulk emails, spam, or email marketing through our network is not allowed.
