+const text = "# Email Bridge\n\nConnect your email to motd. Receive bookmarked content in your inbox. Anyone can email `username@motd.social` and it becomes a public post.\n\n---\n\n## Connect Your Email\n\nIn the motd terminal:\n\n```\n> /connect email\n\n  Enter your email address: you@gmail.com\n\n  Verification email sent to you@gmail.com\n  Click the link in the email to confirm.\n  Tip: add noreply@motd.social to your contacts so notifications don't go to spam.\n```\n\nCheck your inbox. Click the link. Done.\n\nThe link expires after 10 minutes. Type `/connect email` again for a fresh one.\n\n## Disconnect\n\n```\n> /disconnect email\n\n✓ Email disconnected.\n```\n\n---\n\n## Emailing a motd User\n\nAnyone can send an email to `username@motd.social`. The email body becomes a public post in the motd feed with the `[email]` tag.\n\n### Rules\n\n- Only the plain text body is used (HTML is stripped)\n- First 189 characters show in the feed; full post via `/goto`\n- Email signatures are stripped (`--`, `Sent from my iPhone`, etc.)\n- Reply chains (quoted text with `>`) are removed\n- Subject line is ignored\n- Attachments are ignored\n- Maximum 500 characters stored per post\n\n### How it looks\n\nFrom a connected motd user:\n```\n@bob · 5m\n@mika hey saw your project, really clean work\n                                          [email]\n```\n\nFrom an unknown sender:\n```\nemail:john@gmail.com · 5m\n@mika hey saw your project, really clean work\n                                          [email]\n```\n\n### Rate limits\n\nUnknown email senders: 5 emails per hour per address.\n\n---\n\n## Receiving Notifications\n\nWhen your email is connected, you receive emails for:\n\n- New posts from users you bookmarked\n- New posts matching tags you bookmarked\n- Replies to your posts\n- Posts that @mention you\n\n**Not emailed:**\n- The entire feed\n- Posts from killed/filtered users\n- Posts from users with high filter scores\n\n### Email format\n\n```\nFrom: motd.social <noreply@motd.social>\nSubject: @alice on motd.social\n\n@alice · just now\njust shipped the wasm compiler [rust] [wasm]\n\n—\nmotd.social\nReply to this email to post on motd.\n```\n\nPlain text only. Terminal aesthetic even in the inbox.\n\n### Replying to notifications\n\nReply to a notification email and your reply becomes a threaded reply on motd. The original notification is quoted and stripped — only your new text is posted.\n\n---\n\n## Notification Settings\n\nIn `/settings`, connected users see:\n\n```\nEmail notifications: on\n  Notify on: bookmarked users/tags, mentions/replies\n```\n\nToggle each notification type on or off. Email and Telegram notifications are independent.\n\n---\n\n## Long Posts (Read More)\n\nPosts longer than 189 characters show an excerpt in the feed:\n\n```\n@bob · 5m\n@mika hey saw your project, really clean work. I was\nwondering if you considered a different approach to the\nparsing step because...\n                                    [read more · 847 chars]\n                                                    [email]\n```\n\nClick `[read more]` or type `/goto [post_id]` to see the full text. This applies to all posts, not just email.\n\n---\n\n## Server Setup\n\n### Outbound (sending notifications)\n\nOutbound email uses the Brevo transactional API. No local mail server needed.\n\n- API endpoint: `POST https://api.brevo.com/v3/smtp/email`\n- Authenticated via `BREVO_API_KEY` in `.env`\n- Sender: `motd.social <noreply@motd.social>`\n- Free tier: 300 emails/day\n\nDNS records (on INWX for motd.social):\n- SPF: `v=spf1 include:sendinblue.com ~all`\n- DKIM: CNAME `brevo1._domainkey` (via Brevo dashboard)\n- DMARC: `v=DMARC1; p=none; rua=mailto:rua@dmarc.brevo.com`\n\n### Inbound (receiving email as posts)\n\nInbound email is handled by Maddy (mail server already running on the VPS for anomata.eu). Maddy receives email for `motd.social`, then forwards it via SMTP to the motd Node.js app.\n\nFlow: sender → MX → Maddy (port 25) → localhost:2525 → motd SMTP listener → post created\n\nDNS: MX record `motd.social` → `anomata.eu` (priority 10)\n\nMaddy config (`/etc/maddy/maddy.conf`):\n- `motd.social` added to `$(local_domains)`\n- TLS certs loaded for both `anomata.eu` and `motd.social`\n- `target.smtp motd_forward` forwards to `tcp://127.0.0.1:2525`\n- `destination motd.social` in `local_routing` delivers to `&motd_forward`\n- `destination motd.social` in `smtp` block accepts all `*@motd.social` addresses\n\nThe Node app runs an SMTP listener on `127.0.0.1:2525` (started in `server/index.js`). It parses the raw email with `mailparser`, extracts sender/recipient/body, and creates a post.\n\n### Maddy management\n\n```\nsystemctl status maddy          # check status\nsystemctl restart maddy         # restart after config changes\njournalctl -u maddy -f          # live logs\nmaddy creds list                # list mail accounts\n```\n\nConfig: `/etc/maddy/maddy.conf`\nBackup: `/etc/maddy/maddy.conf.bak`\n";
