python - python 的 smtplib 无法连接到 gmail、mail.ru 或其他任何东西

Question

从 line 开始的所有行都返回错误 Errno 10060 或错误 Errno 10061：

import smtplib
server = smtplib.SMTP('smtp.gmail.com:465')
mailServer = smtplib.SMTP("smtp.gmail.com", 587)
mailServer = smtplib.SMTP("smtp.gmail.com", 465)
mailServer = smtplib.SMTP("smtp.mail.ru", 25)
mailServer = smtplib.SMTP("smtp.mail.ru", 2525)

你能帮忙吗？我一定遗漏了一些微不足道的东西......完整的错误消息：

Answer 1

用于smtplib.SMTP_SSL()TLS 连接。

Answer 2

下面的所有命令都没有错；我的问题确实是由 IP 限制引起的。感谢您的所有回答。

Answer 3

或server = smtplib.SMTP('smtp.gmail.com:25')用于正常连接

如果您想从端口 25 获取 tls，只需添加

server.starttls() 

在第一行之后。

ps：由于端口25是默认的，下面是等价的：

server = smtplib.SMTP('smtp.gmail.com')
server.starttls()
