MailKite Mailboxes 0.1.0

Give the people who use your site a real email address on your domain — readable in wp-admin, on the front end, and in any IMAP mail client.

Requires the MailKite SMTP plugin, which provides the account connection and the domain. Install that one first.

Install

Download mailkite-mailboxes.zip below, then in WordPress go to Plugins → Add New → Upload Plugin, choose the file, and activate.

Requires WordPress 6.5+ and PHP 8.1+.

In this first release

• Real addresses on your domain, with IMAP and API credentials on a per-user screen — they work in Apple Mail, Thunderbird, or anything else that speaks IMAP.
• Everything is off until an administrator turns it on: mailboxes, automatic assignment, and letting users pick their own address are three separate switches. Addresses can be reserved so nobody claims admin@ or support@.
• An Inbox screen in wp-admin and a [mailkite_inbox] shortcode for the front end, with Inbox and Sent folders, compose, and threaded replies.
• New mail appears in the open inbox on its own, without reloading the page — so a half-written reply is never thrown away.
• A scheduled catch-up every 15 minutes copies in anything a webhook attempt missed. There is nothing to press.
• Mail is stored in WordPress, so it stays readable after MailKite's retention window ends.

Passes Plugin Check (v2.0.0) with 0 errors and 0 warnings, including experimental checks.
