Python smtplib代理支持

import smtplib
import socks

# 设置代理服务器信息
socks.set_default_proxy(socks.SOCKS5, "proxy_host", proxy_port)
smtplib.SMTP = socks.socksocket

# 连接SMTP服务器并发送邮件
smtp_server = "smtp.example.com"
smtp_port = 587
username = "your_username"
password = "your_password"
sender = "sender@example.com"
receiver = "receiver@example.com"

try:
    server = smtplib.SMTP(smtp_server, smtp_port)
    server.starttls()
    server.login(username, password)
    server.sendmail(sender, receiver, "This is a test email.")
    server.quit()
    print("Email sent successfully!")
except Exception as e:
    print("Failed to send email:", str(e))
