在腾讯云服务器利用python连接gmail发送邮件，为什么一直显示如下错误，之前还能发送的，本地也可以发。也根据网上说的设置了 net.ipv4.ip_nonlocal_bind = 1 还是有问题。有没有大佬解答下。

你的原代码没有传入邮件服务器端口，而是直接传入一个写好的url导致找不到地址，传入端口就可以了，另外记得打开调试模式啊，这样容易判断问题

smtp = smtplib.SMTP_SSL(self.smtp_server, self.port)

# 开启 Debug

smtp.set_debuglevel(True)

# coding=utf-8
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from smtpd import COMMASPACE


class SendEmailByGoogleMail:
    def __init__(self, subject, username, password, receivers:list):
        # 初始化账号信息
        self.user_account = {'username': username, 'password': password}
        # 初始化邮件主题
        self.subject = subject
        # 设置邮箱服务器地址
        self.smtp_server = 'smtp.gmail.com'
        # TLS 容易挂，用SSL端口
        self.port = 465
        # 初始化发件人姓名
        self.sender = ''
        # 初始化收件人邮箱
        self.receivers = receivers

    def send_mail(self, way, content, files):
        msg_root = MIMEMultipart()
        # 构造附件列表
        if files is not None:
            for file in files:
                file_name = file.split("/")[-1]
                att = MIMEText(open(file, 'rb').read(), 'base64', 'utf-8')
                att["Content-Type"] = 'application/octet-stream'
                # 这里的filename可以任意写，写什么名字，邮件中显示什么名字
                att["Content-Disposition"] = 'attachment; filename=%s' % file_name
                msg_root.attach(att)

        # 邮件主题
        msg_root['Subject'] = self.subject
        # 接收者的昵称，其实这里也可以随便设置，不一定要是邮箱
        msg_root['To'] = ';'.join(self.receivers)
        # 邮件正文
        if way == 'common':
            msg_root.attach(MIMEText(content, 'plain', 'utf-8'))
        elif way == 'html':
            msg_root.attach(MIMEText(content, 'html', 'utf-8'))
        smtp = smtplib.SMTP_SSL(self.smtp_server, self.port)
        # 开启 Debug
        smtp.set_debuglevel(True)
        smtp.ehlo()
        # smtp.starttls()
        smtp.login(self.user_account['username'], self.user_account['password'], initial_response_ok=False)
        smtp.auth_plain()
        smtp.sendmail(self.sender, self.receivers, msg_root.as_string())
        print("邮件发送成功")


if __name__ == '__main__':
    sebg = SendEmailByGoogleMail('Hello', username='***', password='***',
                                 receivers=['***'])
    sebg.send_mail('common', content='hello world', files=None)

配置贴一下，之前遇到类似的问题是邮件服务器端口错误导致

邮件发送的类

class SendEmailByGoogleMail:
    def __init__(self, subject, username, password, receivers):

        self.smtp_server = 'smtp.gmail.com:587'
        # 初始化发件人姓名
        self.sender = ''
        # 初始化收件人邮箱
        self.receivers = receivers

    def send_mail(self, way, content, files):
        msg_root = MIMEMultipart()
        # 构造附件列表
        if files is not None:
            for file in files:
                file_name = file.split("/")[-1]
                att = MIMEText(open(file, 'rb').read(), 'base64', 'utf-8')
                att["Content-Type"] = 'application/octet-stream'

        # 邮件正文
        if way == 'common':
            msg_root.attach(MIMEText(content, 'plain', 'utf-8'))
        elif way == 'html':
            msg_root.attach(MIMEText(content, 'html', 'utf-8'))
