disqualifier a44bf11be6 fix: dead is_throttled, orphan connect-task, server-defined folder delimiter (v0.1.4)

- remove is_throttled(): read a non-existent .resp -> always False (dead) (L2)
- cancel/await aioimaplib's fire-and-forget create_connection task on a failed connect
  so a refused host doesn't log 'Task exception was never retrieved' per retry (L3)
- get_folders() parses the server-announced LIST delimiter instead of hardcoding '/',
  so '.'/NIL-delimited servers (Gmail/Dovecot) return correct names (L4)
- mark the dead aioimaplib-2.0.x tuple branch + the non-aioimaplib authenticate
  fallback as cross-version escape hatches (nits).

aiomail

Async IMAP one-time-code retrieval. Reads OTP / login codes out of IMAP mailboxes you own, with password or OAuth2 (XOAUTH2) auth and dynamic sender / subject / code matching.

This reads codes from email; it does not generate them (that is pyotp's job).

Install

requirements.txt:

aiomail @ git+ssh://git@git.rethinkstudios.io/rethink-public/aiomail.git@v0.1.4
# OAuth token providers (Microsoft / Google) need the extra:
aiomail[oauth] @ git+ssh://git@git.rethinkstudios.io/rethink-public/aiomail.git@v0.1.4

Direct:

pip install "aiomail @ git+ssh://git@git.rethinkstudios.io/rethink-public/aiomail.git@v0.1.4"
pip install "aiomail[oauth] @ git+ssh://git@git.rethinkstudios.io/rethink-public/aiomail.git@v0.1.4"

Requires aioimaplib and beautifulsoup4 (pulled transitively). The oauth extra adds aiohttp for the refresh-token providers.

Password auth

from aiomail import IMAPClient, PasswordAuth, retrieve_otp

client = IMAPClient(PasswordAuth(user, password), host="outlook.office365.com")
async with client:
    code = await retrieve_otp(client, sender="no-reply@privy.io", subject="login code")

OAuth2 auth

Pass a static access token, or a token provider that refreshes one on connect:

from aiomail import IMAPClient, OAuth2Auth, retrieve_otp
from aiomail.oauth import MicrosoftTokenProvider

auth = OAuth2Auth(user, token_provider=MicrosoftTokenProvider(client_id, refresh_token))
client = IMAPClient(auth, host="outlook.office365.com")
async with client:
    code = await retrieve_otp(client, sender="no-reply@privy.io")

GoogleTokenProvider(client_id, refresh_token, client_secret) is also provided. Credentials are always supplied by you — nothing is hardcoded.

Dynamic matching

sender and subject accept a substring, a compiled regex, or a callable:

import re
await retrieve_otp(client, sender="uber.com")                      # substring
await retrieve_otp(client, sender=re.compile(r"no-?reply@.*\.io")) # regex
await retrieve_otp(client, sender=lambda f: f.endswith("@x.com"))  # callable

Code extraction is tunable too — patterns (regexes, first group wins) and lengths (standalone digit-run fallback):

from aiomail import extract_code
extract_code(message, patterns=[r"PIN[:\s]+(\d{6})"], lengths=(6,))

Scope

retrieve_otp walks folders newest-first, filters by sender/subject, extracts a code, and applies max_age (seconds; None disables). Provider quirks (folder names, code lengths, freshness) are parameters, not hardcoded branches.

For mailboxes / accounts you own and control.

Verification status

Pure logic (extract_code, as_predicate, retrieve_otp) and the IMAP entrypoints are verified against the installed aioimaplib API. The live-server paths are not fully tested: end-to-end XOAUTH2 login against real Outlook/Gmail, the Microsoft/Google refresh-token exchange (scopes may need adjusting to your app registration), and the iCloud (BODY[]) fetch. Password IMAP and the matching logic work; confirm OAuth end-to-end against your own mailbox before relying on it in production.
