Question

我使用emails库发送邮件，但我还需要将其保存为.msg文件。我已经完成了一些研究，并且还阅读了msg格式规范，偶然发现了this SO answer，它显示了如何将邮件发送到C#中的文件系统，我想知道它是否可以在Python中作为好。

Answer 1

这是可能的，也很容易。让我们假设msg是一个包含所有标题和内容的先前编写的消息，并且您希望将其写入文件对象out。你只需要：

gen = email.generator.Generator(out)  # create a generator
gen.flatten(msg)   # write the message to the file object

完整示例：

import email

# create a simple message
msg = email.mime.text.MIMEText('''This is a simple message.
And a very simple one.''')
msg['Subject'] = 'Simple message'
msg['From'] = 'sender@sending.domain'
msg['To'] = 'rcpt@receiver.domain'

# open a file and save mail to it
with open('filename.elm', 'w') as out:
    gen = email.generator.Generator(out)
    gen.flatten(msg)

filename.elm的内容是：

Content-Type: text/plain; charset="us-ascii"
MIME-Version: 1.0
Content-Transfer-Encoding: 7bit
Subject: Simple message
From: sender@sending.domain
To: rcpt@receiver.domain

This is a simple message.
And a very simple one.

Answer 2

是的，有可能。有用于这些目的的模块，它称为MSG PY。例如：

from independentsoft.msg import Message
from independentsoft.msg import Recipient
from independentsoft.msg import ObjectType
from independentsoft.msg import DisplayType
from independentsoft.msg import RecipientType
from independentsoft.msg import MessageFlag
from independentsoft.msg import StoreSupportMask

message = Message()

recipient1 = Recipient()
recipient1.address_type = "SMTP"
recipient1.display_type = DisplayType.MAIL_USER
recipient1.object_type = ObjectType.MAIL_USER
recipient1.display_name = "John Smith"
recipient1.email_address = "John@domain.com"
recipient1.recipient_type = RecipientType.TO

recipient2 = Recipient()
recipient2.address_type = "SMTP"
recipient2.display_type = DisplayType.MAIL_USER
recipient2.object_type = ObjectType.MAIL_USER
recipient2.display_name = "Mary Smith"
recipient2.email_address = "Mary@domain.com"
recipient2.recipient_type = RecipientType.CC

message.subject = "Test"
message.body = "Body text"
message.display_to = "John Smith"
message.display_cc = "Mary Smith"
message.recipients.append(recipient1)
message.recipients.append(recipient2)
message.message_flags.append(MessageFlag.UNSENT)
message.store_support_masks.append(StoreSupportMask.CREATE)

message.save("e:\\message.msg")

Answer 3

它在Python中是可行的，我尝试了以下代码，它将Outlook文件中的.msg保存在文件夹中。注意：确保outlook具有对目标文件夹的写访问权限，默认情况下，目标文件夹是Python脚本的位置

from win32com.client import Dispatch

outlook = Dispatch("Outlook.Application").GetNamespace("MAPI") 
inbox = outlook.GetDefaultFolder(6)
messages = inbox.items
for msg in messages:
  name = msg.subject
  name = str(name)
  name = name + ".msg"
  msg.saveas(name)

Answer 4

我认为这个问题的答案（但问题不是很清楚，部分内容在评论中）是：

 import email
 from email.message import EmailMessage

如果 msg 是使用 msg = EmailMessage() 创建并填充了适当的调用（参见 https://docs.python.org/3/library/email.examples.html），那么 msg 可以使用

保存

with open('mymessage.msg', 'wb') as f:
            f.write(bytes(msg))

并且可以使用以下方法恢复该文件：

 with open('mymessage.msg', 'rb') as fp:
       msg = email.message_from_binary_file(fp)

在Python中保存为.msg文件，或者将邮件发送到文件系统
