What the service is
Silurian.email Basic and Pro provide ordinary personal or corporate email on a customer domain. Both plans use the same Silurian-operated Mailcow platform in the European Union, so an upgrade can change entitlement without moving the mailbox or changing mail-client settings.
Basic and Pro
Basic is intended for one straightforward mailbox on a Silurian-managed domain. Pro is intended for several users, shared calendars and contacts, guided migration and reviewed external-domain DNS. The exact mailbox, quota, retention and price limits shown in the order control the subscription.
Permitted use
Use the mailbox for normal one-to-one and ordinary team communication with employees, customers, suppliers and other legitimate contacts. Protect account credentials, keep devices secure and report a suspected compromise promptly.
Marketing and bulk mail are separate
Do not connect a newsletter, campaign, lead-generation or marketing-automation application to Basic or Pro. Commercial bulk sends to multiple recipients, mailing lists and purchased or scraped lists are prohibited. A future Silurian.email marketing product will use separate infrastructure, consent evidence and delivery controls.
Connection settings
After activation, use the same secure host on desktop and mobile.
- Incoming mail: mx1-basic-eu.silurian.email, IMAP port 993 with SSL/TLS.
- Outgoing mail: mx1-basic-eu.silurian.email, SMTP port 465 with SSL/TLS or port 587 with STARTTLS.
- Webmail: https://webmail-basic.silurian.email/.
Domain and DNS
The domain must publish the MX and authentication records supplied by Silurian. Silurian can apply them automatically when the domain DNS is managed here; an external DNS provider requires its administrator to publish the exact MX, SPF, DKIM and DMARC records. Do not replace working mail records until the activation plan is confirmed.
Administration from Silurian
The customer Workspace will show the plan, product state, connection settings and platform readiness. Mailbox, alias, password and quota actions will become available only after their audited provider operation and reconciliation flow is enabled. Mailcow administrator access and API keys are never provided to customers.
Security and anomalous activity
Silurian applies mailbox and domain rate limits, filtering and anomaly monitoring to protect customers and delivery reputation. A compromised or abusive account can be restricted immediately while the owner changes credentials and remediates the affected devices or application.
Delivery and recovery
Recipient providers independently filter, delay or reject email, so inbox placement is not guaranteed. Keep independent copies of information you cannot afford to lose. Backup, retention and restoration commitments apply only when they are expressly stated in the order; a running server or redundant disk is not presented as a customer backup.
