Questions & Answers

As answered by people managing Postfix and TrekMail.

Who are some of the biggest customers of your product?

TrekMail's answer:

https://trekguider.com/

What makes your product unique?

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.”

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

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.
