As answered by people managing CloudStack and TrekMail.
TrekMail's answer:
TrekMail's answer:
TrekMail is built for multi-domain email operations: one dashboard to manage many domains and mailboxes with an infrastructure-first approach, pooled storage, practical routing (catch-all/forwarding), and flexible SMTP (managed SMTP or bring your own). It’s optimized for operators (agencies, domain owners), not “per-seat office suites.”
TrekMail's answer:
Choose TrekMail if you want to avoid the per-user tax and need a clean way to run email across multiple domains: faster domain onboarding, centralized admin, migration tooling, and the option to keep your own SMTP stack while still using TrekMail for mailboxes and management.
TrekMail's answer:
Agencies, IT operators/MSPs, small businesses, and domain portfolio owners who manage multiple domains and need reliable business email infrastructure without paying for seats they don’t need.
TrekMail's answer:
TrekMail was created to solve a common ops pain: running professional email on many domains becomes messy and expensive with traditional seat-based suites. TrekMail focuses on the essentials—domains, mailboxes, routing, and migrations—so operators can scale email cleanly from a few domains to hundreds.
TrekMail's answer:
TrekMail is built on a modern web stack: a Laravel/PHP backend, Linux-based mail infrastructure (SMTP/IMAP), and a responsive web UI for admin + webmail access.
