如何在python中保存使用exchangelib库生成的电子邮件消息项

Question

我使用exchangelib库从收件箱下载电子邮件。这些消息最终是exchangelib.items.Message的实例。我想将整个电子邮件保存为.msg文件，以便以后可以将其附加到应用程序中。有人能告诉我如何在python中做到这一点吗？在下面的代码中，我想保存消息列表的每个元素。目前我只处理一封电子邮件。

''

from exchangelib import Account, Configuration, Credentials, DELEGATE
def connect(server, email, username, password):
"""
Get Exchange account cconnection with server
"""
creds = Credentials(username=username, password=password)
config = Configuration(server=server, credentials=creds)
return Account(primary_smtp_address=email, autodiscover=False, config = config, access_type=DELEGATE)
def get_recent_emails(account, folder_name, count):
"""
Retrieve most emails for a given folder
"""
# Get the folder object
folder = account.inbox / folder_name
# Get emails
return folder.all().order_by('-datetime_received')[:count]
account = connect(server, email, username, password)
emails = get_recent_emails(account, 'BSS_IT', 1)
msgs = []
for msg in emails:
msgs.append(msg)

''

Answer 1

我不确定.eml文件的格式是否有公认的标准，但至少有些电子邮件客户端会转储原始MIME内容，该内容在exchangelib中作为Message.mime_content提供。
