我在我的电子邮件中发送了打印机状态报告。我想下载它们并一一处理，并将所有信息放入某个数据库中以供进一步处理。我想在开始学习时使用 python3。我有这个代码：

import getpass
import poplib

server = poplib.POP3('pop3.mailserver.com' )

server.user('report@mailserver.com')
server.pass_('pswd')

numMessages = 1 #len(server.list()[1])
emails, total_bytes = server.stat()

print("{0} emails in the inbox, {1} bytes total".format(emails, total_bytes))

for i in range(numMessages):  
    for msg in server.retr(i+1)[1]:
        print(msg)

我得到的是这种格式的整个电子邮件（带有标题和正文）：

我需要的是逐行处理正文内容，如果匹配，我需要从服务器中删除它。

和提示怎么做？

非常感谢杰拉德

也许如果您从解析消息开始，那将是一个好的开始：

# ... get your message ...
# msg = [b'Return-Path: <"tever">'
#        b'Delivered-To: reportc@mailserver.com', ... ]

import email

# decode simple non-multipart message
message = email.message_from_bytes(b'\n'.join(msg))
payload = message.get_payload(decode=True)
payload = payload.decode(message.get_content_charset())
print(payload)

然后你可以随心所欲地使用有效载荷......
