Introduction
This document provides a comprehensive comparison of VPS providers for hosting mail servers (SMTP servers).
The comparison focuses on key factors relevant to mail server operations, including pricing, features, server locations, and most importantly, mail server specific requirements such as reverse PTR records, IPv6 support, and port 25 restrictions.
Tip
You can set up your own mail server with a self-hosted mail server project, a custom domain name, and a VPS/Dedicated Mail Server provider.
-
Self-Hosted Mail Server Projects: We recommend Forward Email as the preferred self-hosted mail server project to use on your server (you can self-host our entire codebase, however our service is cheaper to simply subscribe to than most providers at only $3/mo – and you can set up your custom domain in seconds!). You may find others at https://github.com/awesome-selfhosted/awesome-selfhosted and https://github.com/Mindbaz/awesome-opensource-email.
-
Custom Domain Name Requirement: You will need a custom domain name in order to use a self-hosted mail server in combination with a provider listed below. We recommend using https://www.cloudflare.com/products/registrar/, https://tld-list.com/, https://namecheap.com, and https://domainr.com/ as resources and providers for finding your custom domain.

Mail Server Specific Features
Reverse PTR Records
Reverse PTR records are critical for mail server operations for the following reasons:
- Authentication and verification of sending servers
- Improved email deliverability
- Spam prevention
- Compliance with email standards
All providers in this comparison support configurable reverse PTR records, which is essential for running a mail server. The process for setting up PTR records varies by provider:
| Provider | PTR Record Configuration | Notes |
|---|---|---|
| DigitalOcean | Via control panel | Simple interface |
| Linode | Via control panel | Well-documented process |
| RackNerd | Via control panel | Quick configuration |
| DataPacket | Via control panel | Standard process |
| DartNode | Directly on network manager | Unique direct configuration |
| UltaHost | Via control panel | User-friendly interface |
| Contabo | Via control panel | Well-documented |
| Hostinger | Via control panel | Simple process |
| RareCloud | Via control panel | Standard configuration |
| OVH | Via control panel | Comprehensive documentation |
IPv6 Support
IPv6 support is becoming increasingly important for mail servers due to:
- Future-proofing as IPv4 addresses become scarce
- Improved routing efficiency
- Enhanced security features
- Compliance with modern standards
All providers in this comparison offer IPv6 support on all their plans, which is beneficial for mail server operations. However, implementation quality may vary:
| Provider | IPv6 Implementation | Notes |

Port 25 Restrictions
Port 25 is the standard SMTP port used for email transmission. Many providers block or restrict this port to prevent spam. This is a critical consideration for mail server hosting:
| Provider | Port 25 Status | Email Sending Limits | Notes |
|---|---|---|---|
| DigitalOcean | Blocked by default | Varies by plan | Can be opened by contacting support with business justification |
| Linode | Open by default | No specific limits | Subject to anti-spam monitoring |

Considerations for Mail Server Hosting
When selecting a VPS provider for mail server hosting, consider:
-
Port 25 Status: Providers with open port 25 by default (RackNerd, DartNode, Linode, Contabo) are preferable for easier setup.
-
Email Sending Limits: Consider your expected email volume and choose a provider with appropriate limits.
-
IP Reputation: Some providers like DigitalOcean may have IPs that are more likely to be blacklisted (e.g. on Spamhaus or UCEPROTECT L2/L3) due to historical spam issues. After being allocated an IP address from a provider, you should check its reputation (e.g. on Spamhaus, Barracuda, ... – see our guide here for more insight: https://forwardemail.net/faq#why-are-my-emails-landing-in-spam-and-junk-and-how-can-i-check-my-domain-reputation).
-
Security History: Providers with clean security records are generally preferable for handling sensitive email data.
-
Geographic Distribution: Choose a provider with server locations that match your target audience for better delivery performance.
Conclusion
All providers in this comparison support the essential mail server requirements of configurable reverse PTR records and IPv6. The main differentiating factors are port 25 restrictions, email sending limits, pricing, and security history. You may find that Reddit, LowEndTalk, and other discussion websites contain more information specific to a provider or a topic (e.g. site:lowendtalk.com port 25 might be a good search query for port 25 restrictions).
For most mail server use cases, RackNerd, Contabo, and Linode offer the best balance of features, price, and mail server compatibility. However, specific needs regarding budget, email volume, and geographic distribution may make other providers more suitable for particular use cases.
Our team uses DataPacket and previously used DigitalOcean and Vultr. We operate baremetal servers with custom AMD Ryzen hardware, NVMe SSD drives, LUKS encryption, and more.
