T-Online IMAP Provider for Backend

File: `backend/providers/mailbox/tonline_imap.py`

Implements BaseMailbox with:

get_email() → returns next unused email from working_mails.txt
wait_for_code(account, keyword, timeout, before_ids, code_pattern) → polls IMAP for OTP
get_current_ids(account) → returns current email UIDs

Critical: MAILBOX_FACTORY_REGISTRY

The backend's core/base_mailbox.py has a hardcoded MAILBOX_FACTORY_REGISTRY dict. New providers MUST be added here:

MAILBOX_FACTORY_REGISTRY = {
    ...
    "tonline_imap": _create_tonline,  # ← MUST add
    ...
}

def _create_tonline(extra: dict, proxy: str | None) -> 'BaseMailbox':
    from providers.mailbox.tonline_imap import TOnlineMailbox
    mails_file = (extra or {}).get("mails_file", None)
    return TOnlineMailbox(mails_file=mails_file)

Critical: CURL_CA_BUNDLE

curl_cffi on Windows needs CA bundle path. Set before starting backend:

import certifi
os.environ["CURL_CA_BUNDLE"] = certifi.where()

Critical: IP Check Bypass

backend/platforms/chatgpt/register.py → _check_ip_location() uses cloudflare.com/cdn-cgi/trace. If it fails, patch to return True, "DE".

Critical: IMAP Search

wait_for_code should search ALL (not UNSEEN) and use targeted FROM search:

status, data = imap.search(None, '(OR FROM "openai" FROM "chatgpt" FROM "noreply")')
if status != "OK" or not data[0]:
    status, data = imap.search(None, "ALL")

Provider Registration via API

PUT /api/provider-settings
{
    "provider_type": "mailbox",
    "provider_key": "tonline_imap",
    "display_name": "T-Online.de IMAP",
    "enabled": true,
    "is_default": true,
    "config": {},
    "auth": {}
}

Create Registration Task

POST /api/tasks/register
{
    "platform": "chatgpt",
    "count": 1,
    "executor_type": "protocol"
}

Pitfalls

PYTHONPATH contamination: Bash shell inherits Hermes venv's PYTHONPATH. Always unset PYTHONPATH before running backend scripts.
Port 8000 conflicts: Multiple backend instances can bind to port 8000. Kill all before restart: netstat -ano | grep ":8000" → taskkill /F /PID XXXX.
DB reset on restart: Backend recreates account_manager.db on restart. Provider settings must be reconfigured via API.
Provider not instantiated: Check MAILBOX_FACTORY_REGISTRY has the provider key. The _loaded flag prevents re-scanning modules.
OTP emails not arriving at t-online.de: Some services (Groq, Blackbox.ai) block t-online.de. ChatGPT OTPs DO arrive but may be delayed.
IMAP search scope: With 39K+ emails in inbox, searching only last 20 misses OTP. Use targeted FROM search or increase to last 50.
ChatGPT login flow requires JS: After OTP validation, ChatGPT returns HTML with JS redirect. Protocol-only (HTTP) approach can't complete the login. Browser-based flow (Camoufox) is needed for the final step.
