Looking for VPS that allows Partial SMTP Handshake for Email Validation

Hello,

We're building a email verification tool that requires outbound connections on Port 25.

This is purely for verification checks - basically just confirming whether an email address is valid and reachable so I can keep lists clean and reduce bounces. No sending, no bulk mail, no spam, nothing shady. It’s literally just a “ping” to the mail server without delivering any content.

If you’re a provider who permits this kind of legit port 25 usage, I'd appreciate if you could reach out with pricing.

Preferring an annual deal.

Thanks in advance.

    We do not block port 25 by default, but we do not allow mail spamming. You can check out our pricing https://rackoona.com/vps-plans

    Warning for all hosting providers here - AVOID.

    Listwashing is the systematic removal of complainants from an illicitly gathered address list with no other action taken to stop spamming the remainder of the list. Listwashing removes spam symptoms without curing the underlying problem. ISPs which simply pass abuse reports on to their spamming customers without investigation or further consequences are aiding in listwashing and spamming. Listwashing is often done in conjunction with snowshoe spamming and waterfalling to attempt to clean bad lists and improve deliverability, rather than simply using OPT IN address acquisition in the first place. Listwashers nearly always include per-recipient codes in the headers and payload URLs. Together with careful list segmentation, dirty lists can be washed to a clean enough state that some ESPs are willing to risk sending spam by importing those lists.

    Ah yeah. Everyone has to be snooping on their neighbors to spot criminals, or they're criminals themselves.

    Sigh.
