Specific technical alignment, not generic copy. Each point below is something the workload needs and we provide by default.

Outbound port 25 unblocked by default. No "we don't allow mail" gotcha.
Reverse DNS editable from the panel — set FQDN per IP without opening a ticket.
IPs pre-checked against Spamhaus + Barracuda + SORBS at provisioning. Clean /29 guaranteed.
Mail-aware DDoS scrubbing on inbound port 25/465/587 — SMTP-level, not just L3.
IPs not recycled from prior mail customers within 12 months. Cooldown documented.
Workload notes

What you should know about Self-hosted mail server on Cryptoservers

Outbound port 25 is unblocked by default — every plan, every location. Reverse DNS is editable from the panel without a ticket. Each new IP is checked against Spamhaus, Barracuda, SORBS and SURBL before it ships, so you start from a clean slate. We allocate from /29s that haven't been recycled from a previous mail customer in the prior 12 months.

Postfix, OpenSMTPD, Exim, Stalwart and ProtonMail Bridge all work without special handling. For inbound IMAP, Dovecot or Cyrus on the same box. SPF/DKIM/DMARC records are your responsibility (we don't provide a managed mail layer); we give you the network and reverse DNS to make them stick.

Sysadmin FAQ

Self-hosted mail server — questions answered

Is the IP I'll get already blacklisted somewhere?
We pre-check Spamhaus DBL/CSS, Barracuda, SORBS and SURBL at provisioning. If the IP shows on any major list at deploy time, we swap it before you log in. After that, it's your sender reputation; we provide neutral terrain.
Can I send marketing email or only transactional?
Both, within limits — any marketing has to be opt-in (we don't host purchased-list senders). If we get a Spamhaus listing on your IP from your traffic, we'll work with you to delist; repeat offenders get re-IPed once and asked to find a managed ESP for bulk.
Do you provide DKIM signing or SMTP relay services?
No managed mail layer. You run Postfix/OpenSMTPD/Exim/Stalwart with your own DKIM keys; we give you the network, the reverse DNS, and unblocked port 25. This keeps the trust model simple — we never see your message bodies.
Can I run a private email service for friends/family on this?
Yes — that's the most common deployment we see. A vps-growth at $26.99/month comfortably handles inbound IMAP for 20–30 mailboxes plus outbound for the same. Dovecot or Cyrus for IMAP; Postfix for SMTP.
What about mail in your chosen jurisdiction specifically — any local restrictions?
your chosen jurisdiction has no local restrictions on outbound port 25 or commercial email beyond standard EU PECR / GDPR for EU jurisdictions. Iceland and Switzerland have lighter regulatory regimes. Practical advice: pick the location closest to your audience for delivery latency.
