VPS with Open Port 25In my email server tutorials, I always use VPS with open port 25 so that I can send emails.

In this article, I will share six reputable VPS providers (which I’ve tested and or contacted their support) known for their open port 25 capabilities and are the best VPS for email servers:

Understanding Ports 25, 587, and 465

Ports 25, 587, and 465 are essential components of the Simple Mail Transfer Protocol (SMTP) and Secure Sockets Layer (SSL)/Transport Layer Security (TLS) protocols. These ports play crucial roles in the transmission and security of email communications:

  1. Port 25: Standard SMTP port for email transmission.
  2. Port 587: Submission port for email clients to send messages securely.
  3. Port 465: Deprecated SSL/TLS port for SMTP over SSL.

Now, let’s explore the features of the VPS providers with open port 25. Not sure your VPS has open port 25? Check it using this tool.

Note: Servers will automatically open their port 25 once an application (e.g. mailcow) that requires open port 25 is installed.

  1. Forget Hostwinds in 2024

    i asked twice before order if i can use port 25. support told me yes.

    the i ordered, installed cyberpanel and got the massage, that my provider blocked port 25!

    after opened a ticket to ask whats wrong, Hostwinds Abuse Department answered me:

    Your account service signup/activities were detected as suspicious by our system. To protect the IP reputation of our network and as a proactive measure to prevent our IP space from being used to distribute unsolicited e-mail(s), Hostwinds reserves the right to apply an SMTP filter as a precaution to accounts flagged by our Abuse Team. Due to this, the SMTP port on your servers has been disabled through a filter placed on your account. This prevents further emails from being sent out from your server.
    We cannot remove the current restrictions that are applied to your account.
    As of now, you will need to submit a request after 90 days have passed since the infraction for the consideration of this removal.

    Ridiculous, sorry….absolutely not recommended

    1. Sorry to hear that. They also told me they open their port 25. Is your domain new and have you installed CyberPanel email server? Did you send email messages after installing?

  2. Hi really loved your content. It’s very comprehensive and beginner-friendly. I was wondering if you are open to reviewing a new VPS provider?

    I found this quite cheap VPS provider with good specs but I am contemplating migrating to this.
