# Python Email Fallback (when himalaya is not installed)
|
|
|
|
When `himalaya` CLI is unavailable, use Python's built-in `smtplib` and `imaplib` with credentials from `~/.hermes/config.yaml`.
|
|
|
|
## Sending Email
|
|
|
|
```python
|
|
import smtplib
|
|
from email.mime.text import MIMEText
|
|
|
|
smtp_host = "claw.163.com"
|
|
sender = "ephronren@claw.163.com"
|
|
password = "<from config>"
|
|
recipient = "recipient@example.com"
|
|
|
|
msg = MIMEText("Body text", "plain", "utf-8")
|
|
msg["From"] = sender
|
|
msg["To"] = recipient
|
|
msg["Subject"] = "Subject"
|
|
|
|
with smtplib.SMTP_SSL(smtp_host, 465) as server:
|
|
server.login(sender, password)
|
|
server.sendmail(sender, recipient, msg.as_string())
|
|
```
|
|
|
|
## Reading Email
|
|
|
|
```python
|
|
import imaplib
|
|
from email import message_from_bytes
|
|
from email.header import decode_header
|
|
|
|
imap_host = "claw.163.com"
|
|
imap_port = 993
|
|
user = "ephronren@claw.163.com"
|
|
password = "<from config>"
|
|
|
|
with imaplib.IMAP4_SSL(imap_host, imap_port) as mail:
|
|
mail.login(user, password)
|
|
mail.select("INBOX")
|
|
_, data = mail.search(None, "ALL")
|
|
ids = data[0].split()
|
|
eid = ids[-1] # latest
|
|
|
|
_, msg_data = mail.fetch(eid, "(RFC822)")
|
|
msg = message_from_bytes(msg_data[0][1])
|
|
|
|
def decode_str(s):
|
|
if s is None:
|
|
return ""
|
|
parts = decode_header(s)
|
|
return " ".join(
|
|
p.decode(c or "utf-8", errors="replace") if isinstance(p, bytes) else p
|
|
for p, c in parts
|
|
)
|
|
|
|
print(f"From: {decode_str(msg['From'])}")
|
|
print(f"Subject: {decode_str(msg['Subject'])}")
|
|
|
|
if msg.is_multipart():
|
|
for part in msg.walk():
|
|
if part.get_content_type() == "text/plain":
|
|
payload = part.get_payload(decode=True)
|
|
charset = part.get_content_charset() or "utf-8"
|
|
print(payload.decode(charset, errors="replace"))
|
|
break
|
|
else:
|
|
payload = msg.get_payload(decode=True)
|
|
charset = msg.get_content_charset() or "utf-8"
|
|
print(payload.decode(charset, errors="replace"))
|
|
```
|
|
|
|
## Pitfalls
|
|
|
|
- **Port 25 times out** — 163 SMTP blocks plain SMTP. Use `SMTP_SSL` with port **465** instead.
|
|
- **Port 465 config mismatch** — config.yaml says port 25, but actual working port is 465.
|
|
- **send_message tool limitation** — `send_message(action='send', target='email:addr@domain')` does NOT resolve external addresses. Must use Python/terminal directly.
|
|
- **IMAP fetch auto-marks as read** — `mail.fetch(eid, "(RFC822)")` and even `fetch(eid, "(BODY[HEADER.FIELDS ...])")` automatically set the `\Seen` flag. If you need to check unread count after reading, the count will drop. Use `mail.search(None, "UNSEEN")` before fetching to get accurate unread count.
