It prepares Cloudflare DNS with MX and SPF records, configures an Email Routing rule, and deploys an edge Worker. Incoming MIME messages, headers, and attachments up to 50 MB route straight to Telegram chats through the Bot API. Setup requires Node.js 20 or newer, an active domain managed by Cloudflare DNS, and an API token. The token must include Zone Read, DNS Edit, Worker Scripts Edit, and Email Routing Rules Edit permissions. A Telegram bot token from `@BotFather` is also mandatory, and the recipient must trigger `/start` beforehand. Once applied, zero code executes locally because the workload runs serverless on Cloudflare edge. Omitting the `/start` message to the Telegram bot causes the setup to fail with a missing chat ID error. ## Install ### Cursor (native platform) **Manually: put the files in place** - File: `.cursor/rules/cloudflare-email-telegram-cursorrules-prompt-file.mdc` — Frontmatter: description, globs, alwaysApply ### Claude Code **Manually: put the files in place** - File: `.claude/rules/cloudflare-email-telegram-cursorrules-prompt-file.md` — The paths frontmatter field limits the files: move globs from the source into paths ### Codex **AGENTS.md** - Codex reads AGENTS.md: paste the rule text there ### GitHub Copilot **Manually: put the files in place** - File: `.github/instructions/cloudflare-email-telegram-cursorrules-prompt-file.instructions.md` — The applyTo field sets which files it applies to: move globs from the source into applyTo ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/rules/cloudflare-email-telegram-cursorrules-prompt-file.md` ### Cline **Manually: put the files in place** - File: `.clinerules/cloudflare-email-telegram-cursorrules-prompt-file.md` Where a file is given instead of a command, copy the files from the source to that path: https://github.com/PatrickJS/awesome-cursorrules/tree/HEAD/rules/cloudflare-email-telegram-cursorrules-prompt-file.mdc ## When to use it - forward domain emails directly to a Telegram chat - configure Cloudflare MX and SPF records automatically - deploy a serverless MIME parser on Cloudflare Workers - send email attachments up to 50 MB to Telegram ## Example prompts - Set up email forwarding from my domain to Telegram using mail2tg - Route incoming mail for info@example.com to Telegram via Cloudflare - Run the mail2tg plan step for my Cloudflare zone ## Source text · cloudflare-email-telegram-cursorrules-prompt-file.mdc · CC0-1.0 Below is the content of a third-party file.

BEGIN THIRD-PARTY FILE a7bb0f3b0d6fe302 ````text --- description: "Cursor rules for setting up email-to-Telegram forwarding via Cloudflare Email Routing and Workers using the mail2tg CLI." globs: **/* alwaysApply: false --- You are an expert at setting up email-to-Telegram forwarding using Cloudflare Email Routing and Workers. When the user asks to set up email forwarding to Telegram, route domain email to Telegram, or mentions "mail2tg", "email to telegram", follow this workflow. ## Tool Use the `mail2tg` CLI published on npm: https://www.npmjs.com/package/mail2tg Source: https://github.com/shatzibitten/mail2tg ## Prerequisites 1. Domain DNS managed by Cloudflare (nameservers pointing to Cloudflare, status "Active"). 2. Cloudflare API token with scopes: Zone Read, DNS Edit, Worker Scripts Edit, Email Routing Rules Edit. Create at dash.cloudflare.com/profile/api-tokens → "Create Custom Token". 3. Telegram bot created via @BotFather, token copied. User has sent /start to the bot. 4. Node.js >= 20. ## Plan-first workflow ```bash export CLOUDFLARE_API_TOKEN="" export TELEGRAM_BOT_TOKEN="" # Replace only after reviewing the npm package and source. MAIL2TG_DOMAIN=example.com \ MAIL2TG_MAILBOX=info@example.com \ npx -y mail2tg@ init --json npx -y mail2tg@ plan --json # Stop here, show the plan to the user, and wait for explicit approval. npx -y mail2tg@ apply --json npx -y mail2tg@ doctor --json ``` ## Interactive workflow ```bash npx -y mail2tg@ init export CLOUDFLARE_API_TOKEN="" export TELEGRAM_BOT_TOKEN="" npx -y mail2tg@ plan # Stop here, show the plan to the user, and wait for explicit approval. npx -y mail2tg@ apply npx -y mail2tg@ doctor ``` ## What it does - Deploys a Cloudflare Worker that parses incoming emails (MIME) and forwards headers, body, and attachments (up to 50 MB) to a Telegram chat via Bot API. - Creates MX and SPF DNS records so Cloudflare receives mail for the domain. - Creates an Email Routing rule directing the configured address to the Worker. - Sets Worker secrets (TELEGRAM_BOT_TOKEN, TELEGRAM_CHAT_ID). After apply, nothing runs locally. Everything is serverless on Cloudflare's edge. Free tier covers 100K emails/day. ## Exit codes - 0: success - 2: missing config or env vars - 3: Cloudflare/Telegram API error - 4: doctor checks failed - 5: worker deployment failed ## Common issues - "Telegram chat_id not found" → user must send /start to the bot, then re-run. - "Cloudflare zone not found" → domain not on Cloudflare or token lacks Zone Read scope. - "Worker deployment failed" → check internet; run `npx wrangler whoami` to debug. ```` END THIRD-PARTY FILE a7bb0f3b0d6fe302 The third-party file has ended.
