Enterprise-Grade Secure Mail Stack.
Achieve absolute email sovereignty and 100% inbox delivery rate. BoostonCP integrates a highly-secured, automated, and hyper-optimized email routing cluster right out-of-the-box.
Email Accounts & Mailbox Hub
Create and manage custom domain email mailboxes with disk storage quotas. Built on Postfix and Dovecot for secure IMAP/POP3 sync across all our [high-performance server nodes](/solutions_servers) for maximum speed.
Smart Email Forwarders
Set up instant forwarding rules to route incoming mails from local domain addresses to external mailboxes (like Gmail, Outlook) instantly, perfectly complementing our [disaster recovery vault](/solutions_disaster_recovery) features.
Domain-Wide Catch-All Manager
Never lose an email due to typos. Route all unrecognized or non-existent email addresses on your domain to a designated mailbox of your choice, or configure it to bounce unrecognized emails automatically.
Automated DNS & Port Configuration
Dynamic generation of SPF, DKIM, and DMARC settings. Provides clear connection guidelines for secure SSL/TLS ports (465/995/993) and recommended STARTTLS ports (587/143/110) that work even without active SSL.
Enterprise SMTP Relay Bridge
Integrate third-party SMTP services (SendGrid, Mailgun, Amazon SES, or Brevo) in one click to route transactional or marketing emails through high-reputation IPs, protecting your local server IP reputation compared to [legacy hosting panels](/compare).
SpamAssassin & Security Shield
Inbound spam protection powered by SpamAssassin. Admins can configure global spam sensitivity score thresholds directly from the dashboard to filter out junk mail, working in tandem with [Sentinel Mode Security](/security) to block malicious threats.
Real-Time Diagnostics & Logs
Monitor outgoing mail queue count and view live Postfix delivery logs. Automatically checks hostname SSL validity and PTR records, showing helpful troubleshooting hints on failures directly in the panel UI.
Integrated Premium Webmail
