maillab/cloud-mail — reverse-engineered prompt

Build me a simple self hosted email service that runs on Cloudflare. I want to use my own domain and create multiple mailbox accounts, kind of like a small Gmail for my domain, but lightweight and cheap to run.

It should have a clean responsive web interface that works on desktop and mobile. Users should be able to log in, read incoming mail, send mail, send to multiple people, use inline images, and upload or download attachments. Admins should be able to manage users and emails, control permissions and limits, and view basic charts about system usage and email growth.

Please include support for Cloudflare Workers, D1, KV, R2, and email routing, with Resend for sending mail. Add optional mail forwarding to Telegram bots or another email address, captcha protection with Turnstile, and automatic detection of verification codes in emails using Workers AI. Also include settings for changing the site title, login background, and appearance.

Look up current Cloudflare docs online if you need to.
