Modoboa installs a whole mail stack with an admin panel, webmail and calendar, and the software is free with unlimited domains and mailboxes. But you run the server, including DNS and deliverability, and help is a paid extra from EUR 120. - **Value for money: C.** Free and open source (ISC licence) with unlimited domains and mailboxes, but only if you host it. Self-hosted free is a C for value. - **Free plan and trial: B.** Free outright. You need your own server to run it, so a B. - **Features: B.** A full stack in one installer: admin panel, webmail, filters, auto-responder, sender reputation tools and monitoring. We found no gap in the mail-server job in the listing. - **Ease of use: D.** No store rating on record. You run the server, DNS and mail delivery yourself, which is a D whatever the quick installer promises. - **Platforms and integrations: C.** Web admin and webmail only, on a server you run. It lists Postfix, Dovecot, Rspamd and Let's Encrypt, but no apps. These are ToolGPA's own grades. Graded from this listing, whose facts were read from Modoboa's own pages on 13 November 2026. Not based on using the product, and shorter than our full reviews. ## Where it stands among email apps - Modoboa's GPA of 2.2 is higher than 29 of the 122 other email apps we grade, and level with 24. - It stands best on features (B, above 79 of 122) and worst on ease of use (D, above 0). - Modoboa has no paid plan. - On features, ease of use and platforms it scores 2.0 out of 4. Nothing scores higher for less, though at least one tool matches that score at a lower price. The category's chart of price against score: https://toolgpa.com/charts/email ## Keep it, or make your own? **Keep it.** Modoboa is free, so making your own would save you nothing. And it is not the kind of software a weekend replaces. That makes this kind of software worth paying for, not this one in particular: 69 of the 122 other email apps grade higher. - You could make: Calendar: an app builder makes this well. - You could not: An email client: sending, receiving, threading and searching years of mail. - You could not: The depth: we grade its features B, which means it covers the whole job. A judgement by ToolGPA from this listing, by rules that are the same for every tool. Nothing was built to test it. ## Works with Postfix, Dovecot, Rspamd, Let's Encrypt **Tags:** Open source, Self-hostable, Email client, Calendar ## Alternatives - [mailcow](https://toolgpa.com/tools/mailcow): Dockerized open-source mail server with a web admin UI.
