Is Port 25 Blocked by Default for Email on Your Servers?

Written by Mingzhi Lin | Sep 30, 2025 3:02:06 PM

No, NovoServe does not block Port 25 (SMTP) or any other ports by default on our dedicated servers.

We believe in providing you with a truly unmanaged, unfiltered connection, giving you complete control and flexibility over your server's configuration. This allows you to run any service you need without arbitrary restrictions.

While all ports are open, it is crucial to understand that the sending of unsolicited bulk email (spam) is forbidden on the NovoServe network. If you plan to operate a mail server, we highly recommend following industry best practices to ensure good email deliverability and protect your IP reputation.
