我正在尝试通过公司SMTP服务器从Azure数据库笔记本发送邮件。我可以在本地计算机上运行相同的脚本。并且从本地运行脚本时正在发送邮件。
但是，当我从数据块运行脚本时，我收到错误 No address associated with hostname
剧本-

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

server = smtplib.SMTP("COMPANY SMTP SERVER", COMPANY_SMTP_PORT)
fromaddr = "username@companyname.com"
toaddr = "username@companyname.com"
msg = MIMEMultipart()
msg['From'] = fromaddr
msg['To'] = toaddr
msg['Subject'] = "Email test"
body = "test mail"
msg.attach(MIMEText(body, 'plain'))
text = msg.as_string()
server.sendmail(fromaddr, toaddr, text)

错误追溯-

gaierror                                  Traceback (most recent call last)

----> 5 server = smtplib.SMTP("COMPANY SMTP SERVER", COMPANY_SMTP_PORT)
      6 fromaddr = "username@companyname.com"
      7 toaddr = "username@companyname.com"

/usr/lib/python3.8/smtplib.py in __init__(self, host, port, local_hostname, timeout, source_address)
    253 
    254         if host:
--> 255             (code, msg) = self.connect(host, port)
    256             if code != 220:
    257                 self.close()

/usr/lib/python3.8/smtplib.py in connect(self, host, port, source_address)
    337             port = self.default_port
    338         sys.audit("smtplib.connect", self, host, port)
--> 339         self.sock = self._get_socket(host, port, self.timeout)
    340         self.file = None

有谁能提供一些见解，可能是什么问题，我如何纠正它？
