description Postal Overview

Postal is a modern, Docker-based mail server solution designed for ease of use and scalability. It offers a clean and intuitive web interface, integrates seamlessly with SOGo for webmail, and provides robust spam filtering and anti-virus capabilities. Postal's focus on automation and streamlined workflows makes it an excellent choice for those seeking a balance between simplicity and power. While it requires some technical proficiency, the Docker-based deployment significantly reduces the complexity compared to traditional mail server setups.

help Postal FAQ

Is Postal a hosted email service or a self-hosted mail server?

Postal is a Docker-based mail-server platform that you deploy and operate on your own infrastructure. It is mainly suited to sending and managing email delivery, so it should not automatically be treated as a complete end-user mailbox suite like a full Mailcow installation.

Does Postal provide webmail through SOGo?

SOGo is a separate groupware and webmail component that can be paired with a mail stack, while Postal itself focuses on mail-server administration and delivery workflows. Treating SOGo as a separate service makes its IMAP, calendar, authentication, and storage requirements easier to plan.

What DNS records are needed before Postal can send mail?

A production setup normally needs correct MX and A records plus SPF, DKIM, DMARC, and reverse DNS or PTR alignment. The sending server also needs a trustworthy hostname and reputation, because Docker deployment alone does not make messages deliver reliably.

How does Postal compare with Mailcow or Mail-in-a-Box?

Postal is a strong fit for programmatic or transactional email delivery, while Mailcow and Mail-in-a-Box are more commonly used as bundled mailbox platforms with IMAP, webmail, and administration components. The right choice depends on whether users need personal inboxes or the application mainly needs authenticated SMTP and delivery tracking.
