为了能够实现邮件发送功能，首先，我们需要了解一下邮件的发送过程是什么样子的，此处不再详细说明，请大家自行搜索或查看https://www.sogouqa.com/?p=438

在了解了邮件的发送过程后，为了实现邮件的全自动匿名发送，我们需要通过windows的命令行，解析邮件的匿名服务器，然后使用匿名服务器，发送邮件到相应的邮箱

代码如下：

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(rmails+exchangers*=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,[])

其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，代码如下：

def _get_internet_address(content):

internet_addresses=re.findall(r(S+)s+internets+addresss*=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，我们需要通过解析出地址的IP，同样，使用windows命令获取结果并正则分析获取IP，代码如下：

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+rs*Addresss*: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

有了邮箱服务器的IP，剩下的事情就是使用IP去发送邮件了，代码比较简单

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 发往如下的邮件失败:,rcpt_to

return False

return True

ok，这样把整个流程整理清楚后，就可以自动发送邮件了
