通过python使用电子邮件库，它只能捕获第一封电子邮件，但不处理其余电子邮件。但这会创建一个单一的msg对象，该对象引用txt文件中的第一封电子邮件。

有没有办法我可以从txt文件中提取所有电子邮件并逐个处理？ msg = email.message_from_file（message）只会获取第一个电子邮件对象。不获取下一条消息obj。

尝试的代码：

    msg = email.message_from_file(message)

    # Dump extra information To, From, Date, Subject header values.
    dump_extra_info(msg)

    decoded_content_list = []
    for part in msg.walk():
        charset = part.get_content_charset();
        if part.get_content_type() == "application/octet-stream":
            logger.info("found content disposition returning ...")
            continue
        decoded_data = part.get_payload(decode=True)
        if decoded_data and charset is not None:
            utf8decoded = decoded_data.decode(charset)
            decoded_content_list.append(utf8decoded)
    return ' '.join(decoded_content_list)```
    ```

使用python从包含多个电子邮件的文本文件中读取所有电子邮件
