Python smtp 协议发送邮件贼鸡儿慢

小弟日常撸 java ，最近上手摸了一下 python ，搞搞自动 docker save 镜像、压缩上传、然后发送邮件通知

到最后一步发送邮件了，用的 smtp 协议，结果发现发送邮件贼鸡儿慢，基本上 35 秒左右，但是我用 java 撸了一发，发现很快啊，5 秒内完事儿

下面是我的代码：

#!/usr/bin/python3 import smtplib import traceback from email.mime.text import MIMEText from email.header import Header def send_html_email(smtp_host, smtp_port, use_ssl, from_addr, from_name, password, to_addrs, cc_addrs, subject, content): try: msg = MIMEText(content, _subtype='html', _charset='utf-8') msg['Subject'] = Header(subject, 'utf-8') msg['From'] = "{}<{}>".format(from_name, from_addr) msg['To'] = ",".join(to_addrs) msg['Cc'] = ",".join(cc_addrs) if use_ssl: smtp = smtplib.SMTP_SSL() else: smtp = smtplib.SMTP() smtp.connect(smtp_host, smtp_port) smtp.login(from_addr, password) smtp.sendmail(from_addr, to_addrs, msg.as_string()) except: print("邮件发送失败") traceback.print_exc() finally: smtp.quit() if __name__ == '__main__': smtp_host = "mail.xxx.com.cn" smtp_port = 25 from_addr = "[email protected]" from_name = "xxx" password = "xxx" to_addrs = ["[email protected]"] cc_addrs = ["[email protected]", "[email protected]"] subject = "python SMTP 测试邮件" cOntent= '<a target="_blank" href="http://192.168.200.128">测试链接</a>' send_html_email(smtp_host, smtp_port, False, from_addr, from_name, password, to_addrs, cc_addrs, subject, content) 

用 126 邮箱、qq 邮箱、公司自己的邮箱发都一样的，35 秒左右，对比 java 5 秒左右，简直无地自容啊，各位彦祖指导一下，问题何在啊？先行谢过了

说错了，代码打印了一下，java 是 500 毫秒左右，之前估算的，应该主观上加了编译的时间
