RoyalSonic Email Use Policy

Operated by J.R.D. Company Ltd. · Established May 2001 · Last revised: July 28, 2026 · Governed by the laws of New Taipei City, Taiwan

This Email Use Policy (“Policy”) outlines the technical, operational, and ethical rules governing all email boxes, SMTP relays, and data transmissions processed through the servers of J.R.D. Company Ltd. (“J.R.D.,” “RoyalSonic,” “we,” “us,” or “our”).

This Policy applies to all individuals and organizations utilizing our network, webmail interfaces, or connecting via standard protocols (IMAP, POP3, SMTP). Violation of this Policy will result in immediate service suspension and data deletion without a refund. This Policy is read together with our Anti-Abuse & Fair Use Policy and Terms of Service. J.R.D.’s determination of a violation is final.

1. Mandatory Domain Authentication & Security Setup

To prevent domain spoofing, identity theft, and spam containment, all custom domains mapped onto the RoyalSonic network must strictly adhere to global authentication standards.

Required DNS Records: Customers are solely responsible for adding and maintaining correct SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance) records at their domain registrar.

Misconfiguration Penalty: RoyalSonic reserves the right to suspend outbound email capabilities for any custom domain that lacks functional SPF or DKIM records. This prevents unauthenticated domains from damaging our shared server IP reputations.

2. Strict Sending Limits & Anti-Spam Framework

Our infrastructure is provisioned strictly for standard relational business operations, team collaboration, and personal communication. Our servers are not a marketing blast platform.

Hourly and Daily Caps: To preserve server stability and prevent IP blocklisting, standard mailboxes are subject to strict outbound message caps. No individual mailbox may transmit more than 100 emails per hour or 500 emails per day unless explicitly granted a dedicated outbound IP addon.

Bulk Mail Prohibitions: Purchased packages cannot be used to distribute newsletters, automated notifications, cold sales outreach lists, or transactional triggers (e.g., automated application signups) from shared IP blocks.

List-Cleaning Requirements: If you utilize an authorized outbound relay for transactional mail, you must maintain clean recipient lists. If your outbound mail generates a bounce rate higher than 5% or a spam complaint rate higher than 0.1%, your entire account will be immediately flagged and throttled by our security filters.

3. Connection and Resource Boundaries

To protect our fast NVMe caches and distributed ZFS storage arrays, connection limits are monitored continuously.

Concurrent Connections: Each individual user account is capped at a maximum of 10 concurrent IMAP connections. Exceeding this threshold via multiple background devices or automated scripts will cause the firewall to temporarily block the offending IP address.

Attachment Constraints: The maximum allowable size for an individual email transmission (including all encoded attachments) is 50 MB. Attempting to send files larger than 50 MB will cause an automated SMTP rejection. For larger file distributions, users must utilize cloud storage links.

4. Zero-Tolerance Inbound/Outbound Abuse

You may not use RoyalSonic servers, webmail panels, or APIs to transmit, forward, or intentionally store content that involves:

• Phishing & Social Engineering: Forging email headers, sender addresses, or reverse-DNS profiles to deceive recipients into verifying credentials or sharing personal info.
• Cryptocurrency & High-Risk Schemes: Distributing unsolicited content relating to crypto-currency manipulation, multi-level marketing (MLM), predatory lending, or gambling.
• Malicious Scripts: Executing, distributing, or storing file attachments containing Trojans, ransomware, macro-viruses, or hidden software exploits.

Accounts terminated for the above forfeit all Fees and LTD value without refund.

5. Automated System Auditing & Enforcement

Automated Threat Scanning: RoyalSonic employs automated server-side filters to analyze inbound and outbound metadata, link paths, and sending frequencies for signs of system compromise or malicious intent. We respect user privacy; our scripts crawl metadata and signature hashes, not private message substance, except as permitted under our Privacy Policy for legal or infrastructure protection.

Instant Containment: If our system detects that your domain or mailbox has been compromised (e.g., a weak password allows a spam bot to hijack an account), we will lock the mailbox instantly without notice to protect the network. Access will be restored only after a password reset and security review via whmcs.royalsonic.com.
