Python写自己主动化之邮件发送（匿名）

为了可以实现邮件发送功能。首先。我们须要了解一下邮件的发送过程是什么样子的，此处不再具体说明，请大家自行搜索或查看

在了解了邮件的发送过程后，为了实现邮件的全自己主动匿名发送，我们须要通过windows的命令行，解析邮件的匿名server。然后使用匿名server，发送邮件到对应的邮箱

代码例如以下：

def _get_mail_exchanger(domain_name,name_server=""):

    #print domain_name

    temp_file=os.getenv("temp")+"\\temp.lsh"

    os.system("nslookup -qt=mx "+domain_name+" "+name_server+" >"+temp_file+" 2>&1")

    f=open(temp_file)

    c=f.read()

    f.close()

    os.remove(temp_file)

    #print c

    internet_addresses_map=_get_internet_address(c)

    mail_exchangers=re.findall(r"mail\s+exchanger\s*=\s*(\S+)",c)

    #mail_exchangers=[internet_addresses_map.get(i,i) for i in mail_exchangers]

    mail_exchangerIPs=[]

    for i in mail_exchangers:

        try:

            mail_exchangerIPs.append(internet_addresses_map[i])

        except:

            ip=_getIP(i)

            if ip:

                mail_exchangerIPs.append(ip)

    if mail_exchangerIPs or name_server:

        print "mail_exchangers",mail_exchangerIPs

        return mail_exchangerIPs

    else:

        print "mail_exchangers from 预配置",g_mail_exchanger.get(domain_name,[])

        return g_mail_exchanger.get(domain_name,[])

当中有个函数用于获取匿名邮箱服务器地址，使用正则分析返回值。代码例如以下：

def _get_internet_address(content):

    internet_addresses=re.findall(r"(\S+)\s+internet\s+address\s*=\s*(\S+)",content)

    internet_addresses_map={}

    for internet_address in internet_addresses:

        internet_addresses_map[internet_address[0]]=internet_address[1]

    return internet_addresses_map

然后，有了地址后，我们须要通过解析出地址的IP，相同，使用windows命令获取结果并正则分析获取IP，代码例如以下：

def _getIP(domain_name,name_server=""):

    temp_file=os.getenv("temp")+"\\temp.lsh"

    os.system("nslookup -qt=a "+domain_name+" "+name_server+" >"+temp_file+" 2>&1")

    f=open(temp_file)

    c=f.read()

    f.close()

    os.remove(temp_file)

    ips=re.findall(domain_name+r"\s*Address\s*:\s*(\S+)",c,re.I)

    if ips:

        return ips[0][0]

    elif name_server=="":

        return _getIP(domain_name,"8.8.8.8")

    else:

        return None

有了邮箱server的IP，剩下的事情就是使用IP去发送邮件了。代码比較简单

def _send_to_mail_exchanger(mail_exchanger,mail_from,rcpt_to,From="",To="",Subject="",Date=None,Body="",attachments=None,encoding="gbk"):

    import smtplib,email

    from email.MIMEMultipart import MIMEMultipart

    from email.MIMEText import MIMEText

    from email.MIMEImage import MIMEImage

    # 构造MIMEMultipart对象做为根容器

    main_msg=email.MIMEMultipart.MIMEMultipart()

    # 设置根容器属性

    main_msg['From'] = From

    main_msg['To'] = To

    main_msg['Subject'] = Subject

    if Date:

	main_msg['Date'] = Date

    else:

	main_msg['Date'] = email.Utils.formatdate()

    # 构造MIMEText对象做为邮件显示内容并附加到根容器

    text_msg = email.MIMEText.MIMEText(Body,'html', encoding)

    main_msg.attach(text_msg)

    # 构造MIMEBase对象做为文件附件内容并附加到根容器

    if attachments:

	for attachment in attachments:

	    if not os.path.isfile(attachment):

		continue

	    if IsImage(attachment):

		try:

		    fp = open(attachment, "rb")

		    file_msg = MIMEImage(fp.read())

		    fp.close()

		    file_msg.add_header("Content-ID", os.path.basename(attachment).replace(".jpg", "").replace(".png", ""))

		    main_msg.attach(file_msg)

		except:

		    pass

	    else:

		file_msg=email.MIMEBase.MIMEBase("application","octet-stream")

		f=open(attachment,'rb')

		file_msg.set_payload(f.read())

		f.close()

		email.Encoders.encode_base64(file_msg)

		file_msg.add_header('Content-Disposition','attachment',filename=os.path.basename(attachment))

		main_msg.attach(file_msg)

    # 用smtp发送邮件

    data=main_msg.as_string()

    for i in range(2):

	try:

	    Log(mail_exchanger)

	    server=smtplib.SMTP(mail_exchanger)

	    Log(mail_from)

	    Log(rcpt_to)

	    ret=server.sendmail(mail_from,rcpt_to,data)

	    break

	except:

	    import traceback

	    Log(traceback.format_exc())

	    ret=False

	    try:

		server.quit()

	    except:

		pass

    try:

	server.quit()

    except:

	pass

    if ret==False or ret:

	#print "发往例如以下的邮件失败:",rcpt_to

	return False

    return True

ok，这样把整个流程整理清楚后，就能够自己主动发送邮件了
