What mail server software can I run on Linode?

Any MTA (Mail Transfer Agent): Postfix (most common), Exim, Sendmail, Haraka, or commercial solutions like PowerMTA. Full root access means no software restrictions.

Does Linode port 25 come with $100 credits?

The port 25 open account ($130) is a separate product from the $100 credit account. The port 25 account provides full Linode access focused on SMTP capability.

Are all Linode regions accessible on the port 25 account?

Yes — full access to all Linode/Akamai global regions including US, EU, Asia-Pacific, and all other available datacentres.

Linode Port 25 Open Account

Linode restricts port 25 (SMTP) on standard accounts to prevent spam. Our pre-verified Linode port 25 open accounts arrive with this restriction already lifted — ready to configure Postfix, Exim, or any SMTP server on Akamai's global cloud network.

About This Feature

Linode (now part of Akamai) blocks outbound port 25 on new accounts as an anti-spam measure. Requesting the removal requires contacting Linode support with a legitimate use case justification — a process that can take several days. Purchasing a Linode port 25 open account from Cloud Accounts ($130) provides immediate SMTP capability. The account gives full Linode access across all global regions, with port 25 pre-unlocked. You can configure mail servers with reverse DNS (PTR records) — an essential requirement for successful email deliverability. Linode's integration with Akamai's CDN network also provides solid routing for mail infrastructure.
