Which providers have port 25 open accounts available?

Cloud Accounts sells port 25 open accounts on DigitalOcean ($99–$299), Linode ($130), IBM Cloud ($80), Kamatera ($45), and Atlantic.Net ($199).

What can I do with a port 25 open account?

Run Postfix, Exim, or any MTA (mail transfer agent) directly on your server, configure SPF/DKIM/DMARC, and send email without routing through a third-party relay.

Is running a mail server from a cloud account allowed?

Yes — for legitimate transactional, business, and personal email. Spam and unsolicited bulk email violates every provider's ToS regardless of port status.

AWS

Cloud Accounts with Port 25 Open

AWS restricts outbound port 25 (SMTP) on all EC2 instances by default to prevent spam. While you can request removal through AWS Support, approval takes days and is not guaranteed. For immediate SMTP access, Cloud Accounts offers open-port accounts on DigitalOcean, Linode, IBM Cloud, Kamatera, and Atlantic.Net.

About This Feature

Port 25 is the standard port used for SMTP communication between mail servers. Cloud providers restrict it on new accounts to prevent newly provisioned servers from being used immediately for spam campaigns — a common abuse pattern. To run a legitimate mail server (Postfix, Exim, Sendmail), SMTP relay, or bulk email infrastructure, you need port 25 to be open on your cloud account. Cloud Accounts sells pre-verified accounts from providers where this restriction is already lifted.

Frequently Asked Questions

Yes — AWS can remove the port 25 restriction via a support request, but it requires a detailed justification and takes 1–5 business days. Not all requests are approved.
