Python：使用smtplib模塊發送電子郵件時未顯示「主題」

Question

我成功地能夠使用smtplib模塊發送電子郵件。但是，當emial發送時，它不包括髮送電子郵件中的主題。

import smtplib 

SERVER = <localhost> 

FROM = <from-address> 
TO = [<to-addres>] 

SUBJECT = "Hello!" 

message = "Test" 

TEXT = "This message was sent with Python's smtplib." 
server = smtplib.SMTP(SERVER) 
server.sendmail(FROM, TO, message) 
server.quit() 

我應該如何編寫「server.sendmail」以在發送的電子郵件中包含SUBJECT。

如果我使用，server.sendmail（發件人，收件人，郵件，分科），它提供了錯誤關於 「smtplib.SMTPSenderRefused」

Answer 1

附上它作爲一個標題：

message = 'Subject: {}\n\n{}'.format(SUBJECT, TEXT) 

然後：

server = smtplib.SMTP(SERVER) 
server.sendmail(FROM, TO, message) 
server.quit() 

還要考慮使用標準Python模塊email - 這將有助於ÿ在撰寫電子郵件時你會做很多事情。

見注在的smtplib文檔的底部：

In general, you will want to use the email package’s features to construct an email message, which you can then convert to a string and send via sendmail(); see email: Examples.

下面是email文檔的示例部分的鏈接，它確實顯示了創建帶有主題行的消息。 http://docs.python.org/library/email-examples.html#email-examples

看來的smtplib並不直接支持主題此外，預計味精已與一個主題，等等。這是在email模塊採用格式化

Answer 3

你或許應該修改代碼以這樣的事：

from smtplib import SMTP as smtp 
from email.mime.text import MIMEText as text 

s = smtp(server) 

s.login(<mail-user>, <mail-pass>) 

m = text(message) 

m['Subject'] = 'Hello!' 
m['From'] = <from-address> 
m['To'] = <to-address> 

s.sendmail(<from-address>, <to-address>, m.as_string()) 

顯然，<>變量必須是實際的字符串值，或者有效的變量，我只是填補他們的佔位符。這適用於發送帶有主題的郵件。

我認爲你必須包括它的消息中：

import smtplib 

message = """From: From Person <from@fromdomain.com> 
To: To Person <to@todomain.com> 
MIME-Version: 1.0 
Content-type: text/html 
Subject: SMTP HTML e-mail test 

This is an e-mail message to be sent in HTML format 

<b>This is HTML message.</b> 
<h1>This is headline.</h1> 
""" 

try: 
    smtpObj = smtplib.SMTP('localhost') 
    smtpObj.sendmail(sender, receivers, message)   
    print "Successfully sent email" 
except SMTPException: 
    print "Error: unable to send email"

試試這個：

import smtplib 
from email.mime.multipart import MIMEMultipart 
msg = MIMEMultipart() 
msg['From'] = 'sender_address' 
msg['To'] = 'reciver_address' 
msg['Subject'] = 'your_subject' 
server = smtplib.SMTP('localhost') 
server.sendmail('from_addr','to_addr',msg.as_string())
