Messaging & domains
Unlimited multi-domain (paid plan)
Host and manage several mail domain names from a single server and a single panel.
Mail accounts & aliases
Creation, deletion, custom disk quotas, on-the-fly enabling/disabling, without ever touching a command line.
Built-in webmail (Roundcube)
Modern mail interface reachable from any browser, included with no extra configuration.
Auto-responder & sorting rules (Sieve)
Automatic replies (out of office, acknowledgement) configurable directly from the admin panel.
Remote mailbox import (IMAP migration)
Automatically bring over the history of a Gmail/Outlook/other-provider account, in the background, with progress tracking.
Smart hourly sending quota
Automatic anti-abuse protection: beyond a threshold, messages are queued rather than rejected, avoiding reputation damage if an account is compromised.
Security & anti-spam
Built-in anti-spam and antivirus filtering (Rspamd + ClamAV)
Every incoming email is scanned before reaching the inbox.
Browsable quarantine
Suspicious messages are not lost: the user or admin can review, release or delete them.
Anti-spam learning (spam train)
The filter improves with the customer's real usage, not a frozen generic model.
Automatic DKIM signing + key rotation
Cryptographic authentication of outgoing emails, with one-click renewal to follow security best practices.
Automatic DNS generation (SPF/DKIM/DMARC/MX)
No DNS expertise needed: the right records are generated and ready to copy at the registrar, drastically reducing the risk of emails landing in spam.
Brute-force protection (fail2ban)
Automatic IP banning after failed login attempts on the webmail.
Manual IP ban list
Direct control to block an identified malicious source.
Firewall and system hardening
"Defense in depth" security posture applied from installation, with no manual work.
Automatic TLS certificates (Let's Encrypt)
HTTPS/SMTPS encryption that is always valid, renewed and checked automatically — zero service interruption caused by an expired certificate.
Monitoring & compliance
Aggregated DMARC reports
Visibility into who sends emails spoofing the customer's domain, a strong argument for compliance and brand protection.
Active blacklist (RBL) monitoring
Alert when the server or a domain gets blacklisted, before the customer notices through lost deliverability.
Continuous DNS check
Automatically detects a broken DNS configuration (often the #1 cause of emails not arriving).
Traffic dashboard
Send/receive statistics viewable by the customer, a real plus over a "black box" mailbox.
Complete one-click diagnostics (selftest)
Server health check, useful for customer support as well as sales demos ("everything is green").
Backups & continuity
Automatic scheduled backups
A peace-of-mind argument for any professional customer.
GPG encryption of backups
Data stays unreadable even if the storage medium is compromised.
Export and sync to remote storage
Protection against total server loss (fire, hardware failure).
One-click restore
Fast business recovery after an incident, a strong selling point against the competition.
Administration & multi-user
Complete web admin panel
No technical skills needed to manage domains, accounts, quotas or backups.
Multiple admin accounts with two-factor authentication (2FA/TOTP)
Stronger security for teams, essential to sell to demanding companies.
Granular roles and permissions
Ability to grant limited access (e.g. technical support) without exposing the whole server — useful for white-label/resale.
Bilingual French/English interface
Immediate opening to an international clientele.
Integrations & automation
Complete REST API with access tokens
Lets you integrate Mailler with an existing CRM, ERP or customer-management platform.
Outgoing webhooks
Automatic notifications (new account, DKIM rotation, etc.) to Slack, a CRM or a billing system — key for agency automation.
Controllable scheduled tasks (cron)
Visibility and control over internal automations (backups, checks, renewals).
Mail queue management
View and purge stuck messages, useful for level-2 support.
Beyond email
Static web page hosting per domain
A mail domain can also serve a simple showcase page, with no additional third-party service.
Built-in phpMyAdmin
Advanced technical access to the database for customers who want it (developer/agency profile).
Reliability & updates
Automatic server update (self-update)
The customer gets the latest security fixes without manual work, with an integrity check (sha256) before applying.
System package version check
Guarantees an always up-to-date software base (Postfix, Dovecot, MariaDB, etc.).
Idempotent, modular installation
Reliable, reproducible deployment on Debian — a technical robustness argument for a reseller/integrator.
