2024 python 脚本收发邮件

在Python中，你可以使用内置的`smtplib`和`email`库来编写脚本来发送和接收电子邮件。以下是基本步骤：

**发送邮件（SMTP）**:

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart

# 邮件配置
smtp_server = "your-smtp-server.com"
port = 587  # 或者465 for SSL/TLS
username = "your-email@example.com"
password = "your-password"

def send_email(recipient, subject, message):
    msg = MIMEMultipart()
    msg['From'] = username
    msg['To'] = recipient
    msg['Subject'] = subject

    body = MIMEText(message, 'plain')
    msg.attach(body)

    server = smtplib.SMTP(smtp_server, port)
    server.starttls()  # 如果需要加密
    server.login(username, password)

    text = msg.as_string()
    server.sendmail(username, recipient, text)
    server.quit()

# 示例用法
send_email("recipient@example.com", "测试邮件", "这是一封测试邮件")

**接收邮件（POP3 / IMAP）**:

import imaplib
from email.parser import BytesParser

# 邮箱配置
imap_server = "your-imap-server.com"
imap_port = 993  # or 143 for non-SSL
username = "your-email@example.com"
password = "your-password"

def fetch_emails():
    mail = imaplib.IMAP4_SSL(imap_server) if imap_port == 993 else imaplib.IMAP4(imap_server)
    mail.login(username, password)
    
    mail.select('inbox')  # 根据邮箱选择合适的标签
    
    status, messages = mail.search(None, 'ALL')
    latest_email_id = messages[0].split()[-1]  # 获取最新邮件ID

    typ, data = mail.fetch(latest_email_id, '(RFC822)')
    raw_email = data[0][1]
    email_message = BytesParser().parsebytes(raw_email)

    # 解析邮件内容
    ...

    mail.close()
    mail.logout()

fetch_emails()

请注意，实际应用中你需要替换上面的服务器地址、端口和用户名密码。此外，处理邮件内容通常会涉及到解析`email.message.Message`对象，根据具体需求提取发件人、主题、正文等信息。
