Business email that
actually reaches the inbox.
Inbound and outbound mail filtered at the network gateway, MailChannels SMTP for deliverability, and a fully managed server underneath. Your IP reputation stays clean from day one.
Getting mail to actually arrive is harder than getting a server to send it.
New IP addresses start with a bad reputation
Fresh VPS IP addresses have no sending history. Major providers like Gmail and Outlook route mail from new IPs straight to spam until reputation is established — which takes months.
One compromised account blacklists your IP
A single account sending spam — from a hacked mailbox or a poorly configured form — can get your entire server IP blacklisted. Recovery takes days.
Spam hits your server before filtering
Server-side spam filters still accept the connection, process the message, and consume resources before rejecting it. High spam volume slows your mail server.
SPF, DKIM, DMARC require expert setup
Proper mail authentication requires correct DNS configuration, private key management, and alignment across records. Misconfiguration causes legitimate mail to bounce.
Mail gateway infrastructure included — not configured by you.
MailChannels SMTP for outbound
All outbound mail routes through MailChannels — a trusted enterprise SMTP relay with established IP reputation. Your server IP is never exposed as the sender.
Rspamd filters inbound at the edge
Spam, phishing, and malware are rejected at the network gateway before they reach your server. Your mail queue stays clean, your server stays fast.
IP reputation protected by design
Because outbound routes through MailChannels, your server IP is never a mail sender. Blacklisting from outbound spam simply cannot happen on your IP.
Managed firewall protects SMTP
Our managed firewall protects SMTP, IMAP, and POP3 ports from brute-force attacks and unauthorized relay attempts — continuously, automatically.

Mail infrastructure most VPS providers leave entirely to you — we handle it.
Most VPS providers give you a server with port 25 open and wish you luck. We include an enterprise mail gateway from day one.
MailChannels SMTP — enterprise deliverability out of the box
MailChannels is whitelisted by Gmail, Outlook, Yahoo, and all major providers. Your outbound mail has established reputation from day one — no months-long warmup period on a fresh IP.
Rspamd at the gateway — spam never hits your server
Most setups filter spam after it arrives. Ours rejects it at the SMTP level before the connection is accepted. Your mail server handles only legitimate traffic — leaner, faster, cleaner.
Your IP can't be blacklisted for outbound spam
When outbound mail routes through MailChannels, your server IP is never the sender. Even if an account is compromised and sends spam, your IP stays clean. Blacklisting is structurally impossible.
Managed firewall protects every mail port
SMTP (25, 587, 465), IMAP (143, 993), and POP3 (110, 995) are protected by our managed firewall and IDS. Brute-force credential attacks on mailboxes are blocked automatically.
Everything your mail server needs — managed from day one.
No mail-specific add-ons. Every feature your mail infrastructure requires is included with every Cloud Cube.
MailChannels SMTP relay
Outbound mail delivery through MailChannels — enterprise relay with established reputation at all major providers. Inbox delivery, not spam folders.
Rspamd inbound filtering
Inbound spam, phishing, and malware rejected at the gateway level. High-volume spam attacks don't consume your server resources.
Managed firewall on all mail ports
All mail ports protected by active firewall rules and IDS. Brute-force attacks blocked automatically — no Fail2ban configuration required.
Proactive mail service monitoring
Postfix, Dovecot, and mail queue health watched 24/7. Service crashes and queue buildups are caught and resolved before they affect delivery.
Mail data backup via S3
Mailbox data and configuration backed up to free offsite S3 storage. Restore to any daily checkpoint without mail loss.
DNS management for mail records
SPF, DKIM, and DMARC records managed through RemarkablePanel DNS. Proper mail authentication setup supported by our team.
Non-oversold infrastructure
Mail servers need consistent CPU and RAM for queue processing. Cloud Cubes don't share resources — your mail performance isn't affected by other tenants.
Free migration from existing mail server
Moving mailboxes from another server or provider? We migrate all accounts, folders, and messages — no data loss during the move.
Self-configured mail vs RemarkableCloud's built-in gateway.
The difference between mail that arrives and mail that doesn't is mostly infrastructure, not content.
| Factor | Typical self-hosted mail | RemarkableCloud |
|---|---|---|
| Outbound IP reputation | New IP — no history, often spam-flagged | MailChannels — established, whitelisted reputation |
| Inbound spam filtering | Server-side — spam loads your queue first | Gateway-level — rejected before reaching server |
| IP blacklisting risk | High — one compromised account blacklists you | None — your IP is never the outbound sender |
| Firewall on mail ports | Manual Fail2ban configuration | Managed IDS — automatic brute-force blocking |
| Mail service monitoring | Manual or self-configured alerts | 24/7 proactive monitoring — outages caught instantly |
| SMTP configuration | Manual relay setup required | MailChannels pre-configured — works from day one |
Your mail server is one part of a complete setup.
Mail that arrives. Managed so you don't have to think about it.
MailChannels SMTP and Rspamd gateway included free on every Cloud Cube. Starting at $2 your first month.
