smtplib.SMTPResponseException：535错误的身份验证数据Apache、python、smtplib modu

Question

我想通过我大学的SMTP服务器发送电子邮件。我写了一些python代码。代码本身运行良好，但我认为SMTP服务器有问题。我想我应该和管理员联系，但我该怎么跟他说呢？这真的是服务器问题吗？我的代码如下所示：

import smtplib
import string

fromaddr = str('from@subunidomain.server.com')
password = str('secretpass')

toaddrs  = 'to@unidomain.com'
server_smtp = 'smtp.server.com'
port_smtp = 465

msg = 'There was a terrible error that occured and I wanted you to know'

BODY = string.join((
        "From: %s" % fromaddr,
        "To: %s" % toaddrs,
        "Subject: %s" % 'Hello' ,
        "",
        'Hello'
        ), "\r\n")

try :

    server = smtplib.SMTP_SSL(host=server_smtp, port=port_smtp)
    server.set_debuglevel(True)
    server.login(fromaddr,password)
    server.sendmail(fromaddr, toaddrs, str(BODY))
    server.quit()

except smtplib.SMTPServerDisconnected :
    print "smtplib.SMTPServerDisconnected"
except smtplib.SMTPResponseException, e:
    print "smtplib.SMTPResponseException: " + str(e.smtp_code) + " " + str(e.smtp_error)
except smtplib.SMTPSenderRefused:
    print "smtplib.SMTPSenderRefused"
except smtplib.SMTPRecipientsRefused:
    print "smtplib.SMTPRecipientsRefused"
except smtplib.SMTPDataError:
    print "smtplib.SMTPDataError"
except smtplib.SMTPConnectError:
    print "smtplib.SMTPConnectError"
except smtplib.SMTPHeloError:
    print "smtplib.SMTPHeloError"
except smtplib.SMTPAuthenticationError:
    print "smtplib.SMTPAuthenticationError"
except Exception :
    print "Exception"

我从服务器上得到这样的回应：

^{pr2}$

有什么问题，怎么解决？我的密码和电子邮件100%正确。

也许您可以尝试使用yagmail发送消息。在

安装：

pip install yagmail

然后导入、创建连接对象并发送电子邮件：

import yagmail
yag = yagmail.Connect('user', 'pass', server_smtp, port_smtp, set_debuglevel = 1)
yag.send(toaddrs, Subject = 'Hello', Body = 'Hello')

如果你遇到任何错误，请告诉我。在

免责声明/背景：我是yagmail的维护者/开发人员。 这个软件包的目的是让很多东西在发送电子邮件时非常方便。例如，您可以使用它的特性不在脚本中写入密码，而是将其存储在keyring中（非常安全，您可以在github上阅读）。 它还有一些方法可以使它变短，例如：

^{pr2}$

附件（例如HTML/images）非常容易使用，但我不会去那里，因为它没有被要求。最后，一旦超出范围，它就会自动退出。在
