Python3-EC2-smtplib-OVH：错误“ [Errno 104]对等重置连接”

问题描述

在python3中使用smtplib我在AWS的ec2机器上使用它时遇到了问题

我正在使用以下功能：

def ovh_send_email(sender_name,sender_address,recipient_addresses,subject,body_text,body_html,attachments = []):

mail_username = u'[e-mail]'
mail_password = u'XXXXXXXXXXXXXXXXXX'
mail_smtp_server = "ssl0.ovh.net"
mail_smtp_port = 465

session = smtplib.SMTP_SSL(mail_smtp_server,mail_smtp_port) #Initiate connection to the server
session.set_debuglevel(1)

session.ehlo() #Start encrypting everything you're sending to the server
session.login(mail_username,mail_password) #Define the recipient of the email

msg = MIMEMultipart('mixed')
msg['Subject'] = subject
msg['From'] = sender_name + " <" + sender_address + ">"
msg['To'] = ",".join(recipient_addresses)

html = body_html

part2 = MIMEText(body_html,'html','utf-8')


for attachment_name in attachments:
    attachment = MIMEApplication(attachments[attachment_name])
    attachment.add_header("Content-disposition","attachment",filename=attachment_name)
    msg.attach(attachment)


msg.attach(part2)


session.sendmail(mail_username,msg.as_string())#Close the connection to the SMTP server 
session.quit()

我得到的是

Exception Type: ConnectionResetError at /contact-email
Exception Value: [[Errno 104] Connection reset by peer

我也尝试使用587端口发送不带ssh的邮件，但问题仍然存在

奇怪的是，当我直接从终端运行ovh_send_email函数时，它在另一台EC2上没有发生剂量

一旦我在终端机上得到了它，但是我再尝试了一段时间后就再也没有看到它...

ovh_send_email(sender_name,body_html)
Traceback (most recent call last):
  File "<stdin>",line 1,in <module>

    self._sslobj.do_handshake()
ConnectionResetError: [Errno 104] Connection reset by peer

有什么帮助的想法吗？ THX !!!

解决方法

由于smtplib没有任何具体的超级安全证书（通过gmail或其他邮件引擎发送电子邮件），因此您被邮件提供商阻止。问题不在您的代码或端口上。

您可以执行以下操作：

• 转到您的邮件设置
• 转到邮件的安全设置
• 启用安全性较差的应用访问电子邮件

你应该很好！

我考虑过这一点，并将深入研究这个想法

我觉得奇怪的是 •有时我得到同级重置的[Errno 104]连接 •有时候我不……我是说它有用

示例：

first try --> [Errno 104] Connection reset by peer
second try -- > OK
third try -- > OK
4th try --> [Errno 104] Connection reset by peer
5th try -- > OK

以此类推！
