在电子邮件Python中嵌入图像

Question

下面给出了使用python发送图像嵌入式电子邮件的代码.

from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText
from email.MIMEImage import MIMEImage

# Define these once; use them twice!
strFrom = 'from@sender.com'
strTo = 'to@example.com'

# Create the root message and fill in the from, to, and subject headers
msgRoot = MIMEMultipart('related')
msgRoot['Subject'] = 'test message'
msgRoot['From'] = strFrom
msgRoot['To'] = strTo
msgRoot.preamble = 'This is a multi-part message in MIME format.'

# Encapsulate the plain and HTML versions of the message body in an
# 'alternative' part, so message agents can decide which they want to display.
msgAlternative = MIMEMultipart('alternative')
msgRoot.attach(msgAlternative)

msgText = MIMEText('This is the alternative plain text message.')
msgAlternative.attach(msgText)

# We reference the image in the IMG SRC attribute by the ID we give it below
msgText = MIMEText('<b>Some <i>HTML</i> text</b> and an image.<br><img src="cid:image1"><br>Nifty!', 'html')
msgAlternative.attach(msgText)

# This example assumes the image is in the current directory
fp = open('test.jpg', 'rb')

msgImage = MIMEImage(fp.read())
fp.close()

# Define the image's ID as referenced above
msgImage.add_header('Content-ID', '<image1>')
msgRoot.attach(msgImage)

# Send the email (this example assumes SMTP authentication is required)
import smtplib
smtp = smtplib.SMTP()
smtp.sendmail(strFrom, strTo, msgRoot.as_string())
smtp.quit()

我的问题非常特定于接收方电子邮件服务器.我使用相同的代码向GMail id 发送电子邮件.它工作正常.但是在这里,每当我尝试在电子邮件中嵌入图像时,接收方电子邮件服务器都将此电子邮件视为垃圾邮件,如上面的代码所示.如果我没有尝试嵌入图像,则会按预期在目的地收到html和纯文本电子邮件.我还尝试使用静态http网址嵌入图像作为图像src.但那时问题也存在.但是,当我尝试使用一些https图像网址时,接收方正确收到的电子邮件.

接收方端邮件过滤由postini提供支持.

可能是什么问题？有什么方法可以修改上面的代码来摆脱这个问题.

谢谢.

您可以看看这个答案： Python: Mail sent by script is mark as spam by Gmail

另一种选择 - 避免被标记为垃圾邮件 - 是使用 AWS SES 等服务。
