尝试使用 Python 通过 GoDaddy 发送电子邮件

Question

这是我用来通过 GoDaddy 发送电子邮件的代码：

import smtplib

server = smtplib.SMTP('smtpout.secureserver.net', 465)
server.starttls()
server.ehlo()
server.login("username", "password")
msg = "Please work!!!!!!"
fromaddr = "fromemail"
toaddr = "toemail"
server.sendmail(fromaddr, toaddr, msg)

运行脚本时，我收到此错误：

Traceback (most recent call last):
File "emailTest.py", line 3, in <module>
server = smtplib.SMTP('smtpout.secureserver.net', 465)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/smtplib.py",      line 250, in __init__
(code, msg) = self.connect(host, port)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/smtplib.py", line 311, in connect
(code, msg) = self.getreply()
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/smtplib.py", line 362, in getreply
raise SMTPServerDisconnected("Connection unexpectedly closed")
smtplib.SMTPServerDisconnected: Connection unexpectedly closed

我真的很迷茫，我知道我的登录信息是正确的。

Answer 1

替换这两行：

server = smtplib.SMTP('smtpout.secureserver.net', 465)
server.starttls()

与这两个：

server = smtplib.SMTP_SSL('smtpout.secureserver.net', 465)
#server.starttls()

引用文档：

SMTP_SSL 应用于从连接开始就需要 SSL 且不适合使用 starttls() 的情况。

使用端口 465 就是其中一种情况。SMTP.starttls()当您使用端口 25 或端口 587 时适用。

Answer 2

如果有人对符合 RFC 5322 的电子邮件有问题，这最终对我有用：

import smtplib
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText

msg = MIMEMultipart()
msg.set_unixfrom('author')
msg['From'] = 'you@mail.com'
msg['To'] = 'them@mail.com'
msg['Subject'] = 'simple email in python'
message = 'here is the email'
msg.attach(MIMEText(message))

mailserver = smtplib.SMTP_SSL('smtpout.secureserver.net', 465)
mailserver.ehlo()
mailserver.login('yourgodaddy@mail.com', 'PASSWORD')

mailserver.sendmail('you@mail.com','them@mail.com',msg.as_string())

mailserver.quit()
