使用python smtplib向self发送电子邮件

Question

你需要一些关于python smtplib的帮助。代码按以下方式工作

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart

sender = "sender@abc.com"
subject = "Test Email"
to_list = ["recipient@xyz.com"]
cc_list = ["sender@abc.com"]
bcc_list = ["sender@abc.com"]

msg = MIMEMultipart('alternative')
body = "<B> This is </B> a test message"
emailbody = MIMEText(body, 'html')
msg.attach(emailbody)

msg['Subject'] = subject
msg['From'] = sender
msg['To'] = ",".join(to_list)
msg['Cc'] = ",".join(cc_list)


recipients = to_list + cc_list + bcc_list

s = smtplib.SMTP('localhost')
s.sendmail(sender, recipients, msg.as_string())

代码有效，并且能够由收件人接收。但是，cc和/或密件抄送不会收到电子邮件，而是发送给自己。在linux2上使用Python 2.6.6 /（Red Hat 4.4.7-17）]

[编辑]

我有点孤立了这个问题。如果我使用xx@abc.com作为发件人，xx @ abc.com和xx@xyz.com将能够收到该电子邮件。但是，当我使用 xx@xyz.com 作为发件人时，只有 xx@abc.com 才能收到该电子邮件。这可能是SMTP服务器上的问题，还是我可以在smtplib中使用任何参数？以下是输出注意：我已经用xxxxxxxxxx :)替换了一些信息：
