VPS for smtp

You should rent a dedicated server to run a mail server. A dedicated server will be more powerful and fully support all your requirements.

You should look for reputable VPS or dedicated server providers that explicitly allow SMTP/PowerMTA use, provide multiple dedicated IPs, rDNS control, and support CentOS because many generic VPS hosts block port 25 or don’t let you set reverse DNS by default to prevent spam issues. Providers like Hetzner, SoYouStart, Leaseweb, or OVH are often recommended because they let you add extra IPs and configure rDNS yourself, and don’t block SMTP out of the box (just make sure you request it enabled). Just be aware that sending bulk mail can trigger abuse checks, so pick a host with clear policies on email sending to avoid account suspensions.

When looking for a **VPS for SMTP**, the key is finding a host that **doesn’t block port 25**, lets you add **multiple static IPs**, and gives you control over **rDNS/SPF/DKIM/DMARC** so your mail isn’t treated as spam. Generic cheap VPS providers often block outbound SMTP or restrict it, so it’s worth choosing one with clear email-friendly policies even if the price is a bit higher. Personally I’d prefer a provider known for allowing full mail server setup rather than struggling with restrictions later reliability and reputation matter more than just the lowest cost.

For a **VPS for SMTP**, the biggest things to check are: no blocked port 25, ability to add **multiple dedicated IPs**, reverse DNS control, and clean reputation otherwise your mail will land in spam or get throttled. Many generic VPS providers restrict SMTP or block it entirely, so choosing a host that *explicitly allows* outbound mail and gives you full DNS/IP control is worth it. In my view, paying a bit more for a reliable provider with good abuse policies and support beats struggling with cheap hosts that throttle or suspend accounts.

1. Port 25/587 open by default or on request. Some providers will open it after a support ticket — that's fine and actually a good sign, it means they care about keeping their IP ranges clean. Avoid providers that flat-out refuse.
2. rDNS (PTR record) you can set yourself — either through a control panel or via support ticket. This is non-negotiable for any SMTP setup. If they can't do per-IP rDNS, walk away.
3. Additional IPs available. You'll want at least a few for IP rotation with PowerMTA. Check if they charge per IP and whether the IPs come from clean ranges (not already blacklisted). Before you buy, check their ASN on MXToolbox or Spamhaus — if the whole range is dirty, extra IPs won't help.
4. European providers tend to be more SMTP-friendly than US-based ones. France and Netherlands in particular have good options. Look for small-to-mid providers that explicitly mention "email hosting" or "mail server" in their product pages.
5. CentOS note: CentOS 7 is EOL, and CentOS Stream isn't ideal for production mail. Consider AlmaLinux or Rocky Linux instead — both are drop-in replacements and PowerMTA runs on them without issues.
