Control Panel Emails Blocked, Since Port 25 is Blocked in All Droplets!

About the blocking of port 25 on droplets. I am concerned that this is preventing me from receiving important emails from my control panel.

I understand that DigitalOcean blocks port 25 by default in an effort to combat spam. However, in my case, I need to be able to receive emails from my control panel in order to stay informed about any issues with my droplets.

I am currently using Google Workspace for business emails and Brevo (formerly known as SendInBlue) for transactional website emails. I do not want to set up port 25 for emails from my control panel because it would require a significant amount of time and effort, and it would also add unnecessary email bandwidth.

I would like to know if there is a way to enable port 25 for emails from my control panel, or if there is a workaround that would allow me to receive these emails on a different port, such as 2525.

Unfortunately, we don’t allow the unblocking of port 25 at the moment due to reasons you’ve mentioned such as combating spam, maintaining a high reputation for our IPs and ensuring deliverability of emails from our network.

Heya @shaerif,

You can contact DigitalOcean’s support and ask and explain to them why you need port 25 opened. You can reach them here:

However, receiving emails is typically done using other ports, such as:

  1. Port 110: POP3 (Post Office Protocol version 3) - This is an older protocol for receiving emails. It’s used to download emails from a server to your email client (e.g., Outlook, Thunderbird), and the default port is 110.

  2. Port 143: IMAP (Internet Message Access Protocol) - IMAP is a more modern protocol that allows multiple devices to access the same mailbox and keeps emails synchronized. The default port for IMAP is 143.

  3. Port 995: Secure POP3 (POP3 over SSL) - This is the encrypted version of POP3, and it uses port 995 for secure email retrieval.

  4. Port 993: Secure IMAP (IMAP over SSL) - Similar to secure POP3, this is the encrypted version of IMAP, and it uses port 993.

So, while you won’t typically use port 25 to receive emails, you might use it to send emails from your email client or server to an SMTP server for onward delivery. Receiving emails is done through ports like 110, 143, 995, or 993, depending on whether you’re using POP3 or IMAP, and whether you’re using secure connections.

Hope that helps! - KFSys.
