python - 服务器不支持 SMTP AUTH 扩展

Question

使用 python 我想从我的应用程序发送电子邮件，但它显示错误

SMTP AUTH extension not supported by server

程序代码，

import smtplib
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText
fromaddr = "test1@example.com"
toaddr = "test2@example.com"
msg = MIMEMultipart()
msg['From'] = fromaddr
msg['To'] = toaddr
msg['Subject'] = "Test Mail"
body = "Test mail from python"
msg.attach(MIMEText(body, 'plain'))
server = smtplib.SMTP('smtp.example.com', 25)
server.ehlo()
server.starttls()
server.ehlo()
server.login(fromaddr, "password")
text = msg.as_string()
server.sendmail(fromaddr, toaddr, text)
server.quit()

Telnet 输出:

ehlo test1.example.com
250-hidden
250-HELP
250-SIZE 104857600
250-ENHANCEDSTATUSCODES
250-8BITMIME
250-STARTTLS
250 OK

我需要验证并从应用发送邮件。

Answer 1

在登录和发送电子邮件之前需要连接。

server = smtplib.SMTP('smtp.example.com', 25)
server.connect("smtp.example.com",465)
server.ehlo()
server.starttls()
server.ehlo()
server.login(fromaddr, "password")
text = msg.as_string()
server.sendmail(fromaddr, toaddr, text)
server.quit()
