python实现转发指定邮件到指定人

要在Python中实现转发指定邮件到指定人，你可以使用IMAP协议来检索邮件，然后使用smtplib和email模块来转发邮件。以下是一个示例：

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

def forward_email(sender, password, recipient, subject, message):
    # 配置发件人和收件人信息
    msg = MIMEMultipart()
    msg['From'] = sender
    msg['To'] = recipient
    msg['Subject'] = subject

    # 添加邮件正文
    body = MIMEText(message, 'plain')
    msg.attach(body)

    # 建立SMTP连接并发送邮件
    with smtplib.SMTP('smtp.gmail.com', 587) as server:  # 使用Gmail SMTP服务器作为示例
        server.starttls()
        server.login(sender, password)
        server.send_message(msg)

def retrieve_email(username, password):
    # 建立IMAP连接并登录
    with imaplib.IMAP4_SSL('imap.gmail.com') as mail:
        mail.login(username, password)

        # 选择收件箱
        mail.select('inbox')

        # 搜索特定的邮件
        status, data = mail.search(None, 'ALL')

        # 获取最新的邮件ID
        mail_ids = data[0].split()
        latest_mail_id = mail_ids[-1]

        # 获取最新的邮件内容
        status, data = mail.fetch(latest_mail_id, '(RFC822)')
        raw_email = data[0][1]

        # 解析邮件内容
        email_message = email.message_from_bytes(raw_email)

        # 获取发件人、主题和正文
        sender = email_message['From']
        subject = email_message['Subject']
        body = ""

        if email_message.is_multipart():
            for part in email_message.walk():
                content_type = part.get_content_type()
                if content_type == 'text/plain':
                    body = part.get_payload(decode=True)
                    break
        else:
            body = email_message.get_payload(decode=True)

        return sender, subject, body

# 设置发件人和收件人信息
sender_email = 'your_email@gmail.com'  # 发件人邮箱
sender_password = 'your_password'  # 发件人邮箱密码
recipient_email = 'recipient_email@example.com'  # 收件人邮箱

# 检索最新的邮件
sender, subject, body = retrieve_email(sender_email, sender_password)

# 转发邮件
forward_email(sender_email, sender_password, recipient_email, subject, body)

以上示例使用了Gmail作为收发邮件的示例，你可以根据需要修改为其他邮件服务器的配置。请确保在使用该代码之前，已经开启了发件邮箱的SMTP和IMAP服务，并且输入了正确的发件人邮箱和密码。
