Question

我复制并粘贴了这个示例并填写了我自己的电子邮件地址。

# Import smtplib for the actual sending function
import smtplib

# Import the email modules we'll need
from email.mime.text import MIMEText

# Open a plain text file for reading.  For this example, assume that
# the text file contains only ASCII characters.
fp = open('/Users/Jon/dev/iit/test-tools/logs/practice_tests.test_one.log', 'rb')
# Create a text/plain message
msg = MIMEText(fp.read())
fp.close()

me = 'Jon@MacBookPro.com'
you = 'jon.drowell@yahoo.com'

# me == the sender's email address
# you == the recipient's email address
msg['Subject'] = 'The contents of the log file'
msg['From'] = me
msg['To'] = you

# Send the message via our own SMTP server, but don't include the
# envelope header.
s = smtplib.SMTP('localhost', 1025)
s.sendmail(me, [you], msg.as_string())
s.quit()

然后我打开另一个终端窗口并运行以下命令：

python -m smtpd -n -c DebuggingServer localhost:1025

当我运行文件发送电子邮件时，它完成没有错误，并且运行python -m smtpd -n -c DebuggingServer localhost:1025命令的终端打印出一个看起来正确的好日志消息：

---------- MESSAGE FOLLOWS ----------
Content-Type: text/plain; charset="us-ascii"
MIME-Version: 1.0
Content-Transfer-Encoding: 7bit
Subject: The contents of the log file
From: Jon@MacBookPro.com
To: jon.crowell@yahoo.com
X-Peer: 127.0.0.1

line one
line two
line three
------------ END MESSAGE ------------

但是当我查看我的雅虎电子邮件地址时，电子邮件永远不会到来。我等了大约5分钟，我觉得这已经足够了。我做错了什么？

Answer 1

来自smtpd documentation

class smtpd.DebuggingServer（localaddr，remoteaddr）创建一个新的调试服务器。参数是根据SMTPServer。 邮件将被丢弃，并打印在stdout上。

Answer 2

调试邮件消息并查看幕后信息的好方法，只需设置smtp对象的debuglevel：

debuglevel = True
mail = smtplib.SMTP(SMTP_SERVER, SMTP_PORT)
mail.set_debuglevel(debuglevel)
mail.starttls()
mail.login(SMTP_USERNAME, SMTP_PASSWORD)
mail.sendmail(EMAIL_FROM, EMAIL_TO, msg.as_string())
mail.quit()

这使您可以在此过程中查看步骤/检查：
