Best Cloud Accounts for Email Servers
Running a mail server requires port 25 access, reverse DNS, and a cloud provider that doesn't block SMTP. These accounts are specifically pre-configured with port 25 open — no waiting for support requests or approval processes.
- Our #1 pick for email servers is the DigitalOcean Open Port 3 Droplet.
- Strong runners-up include the Kamatera Port 25 Open and Linode Port 25 Open.
- Key requirement: port 25 (smtp) outbound access — must be pre-unlocked.
- Every recommended account is verified, delivered within hours, and backed by a 7-day guarantee.
What You Need
- Port 25 (SMTP) outbound access — must be pre-unlocked
- Reverse DNS (PTR record) configuration for deliverability
- Static IP addresses for consistent sender reputation
- SSD storage for fast mail queue processing
- Sufficient bandwidth for high-volume sending
Buying Guide
For mail server hosting, port 25 access is non-negotiable — never try to use a standard account and fight for port 25 approval. Buy a pre-configured open-port account from the start. Set up SPF, DKIM, and DMARC records immediately after provisioning — email without these three records will hit spam folders regardless of your cloud provider. For high-volume sending (10,000+ emails/day), the DO Open Port 25 account (25 droplets) lets you distribute load across multiple IPs and avoid single-IP blacklisting.

Cloud providers block port 25 on new accounts to prevent immediate spam abuse. Legitimate mail server operators must either request removal (slow, may be denied) or buy pre-configured accounts from Cloud Accounts.
