About

A self-hosted alternative to Roundcube.

Self-hosted multi-domain webmail on one Worker: mailboxes and users on your own domains through Email Routing, sending through Resend or SendFlare, and external Gmail, Microsoft and other accounts in one place. The interface is in Chinese.

Features

  • Create mailboxes for several domains in one browser workspace
  • Read connected Gmail, Microsoft and other supported inboxes
  • Send messages and replies with a Resend or SendFlare account
  • Search messages by sender, subject or body
  • Invite users and set mailbox storage quotas
  • Translate messages on request with Workers AI

Deploy OmniMail on Cloudflare

  1. Step 1: Set up Appflare in your Cloudflare account

    Once

    Appflare installs itself into your own Cloudflare account from your browser, and runs on the free Workers plan, as OmniMail does. See what OmniMail needs on your account.

    Set up AppflareAlready have Appflare? Install OmniMail

  2. Step 2: Install OmniMail

    The install form asks you for:

    • Super administrator email
    • A domain of yours that can receive email

    Appflare generates three values for you: Setup token, Mail credentials key and Two-factor encryption key.

    It also has 11 optional settings you can leave for later.

    One switch on the form puts OmniMail behind Cloudflare Access, so only the people who use your Appflare can open it.

  3. Step 3: Finish setting it up

    After the install, Appflare shows three short steps for OmniMail, on its page.

With Appflare instead of by hand

  • Nothing to build on your computerAppflare sets itself up from your browser, with no API token to create and nothing to install.
  • Updates in one clickAppflare tells you when the catalog has a new version, and Update installs it.
  • Health checksAfter every install and update, Appflare checks that the app answers.
  • It stays in your own accountEverything runs on your Cloudflare account and your plan, and Appflare records what it creates, so an uninstall removes it.

Questions

Does OmniMail run on Cloudflare's free plan?

Yes. OmniMail runs on Cloudflare's free Workers plan, and so does Appflare.

What does OmniMail create in my Cloudflare account?

Appflare creates a Worker for OmniMail and the resources it uses: D1 databases, R2 buckets, queues, Workflows and cron triggers. It also uses Workers AI, Email Routing and a domain. Appflare records each resource it creates; an uninstall deletes them, keeping any data you choose to keep.

How do I update OmniMail?

When the catalog has a new version, OmniMail's page in Appflare says Update available. Select Update: Appflare takes a snapshot first, so you can roll back to the version before. You can also let Appflare update it automatically.

Is OmniMail open source?

Yes, under MIT. An open-source license: you may use, change and share the app on its terms. Its source code is at github.com/mibgb65-cloud/OmniMail.
