用socket发送匿名邮件之python实现
#coding:utf-8 from socket import *msg = "\r\n I love computer networks!" #需要发送的数据
endmsg = "\r\n.\r\n"
# Choose a mail server (e.g. Google mail server) and call it mailserver
mailserver = ("163mx02.mxmail.netease.com",25)#Fill in start #Fill in end
# Create socket called clientSocket and establish a TCP connection with mailserver
#Fill in start
clientSocket = socket(AF_INET, SOCK_STREAM)
clientSocket.connect(mailserver)
#Fill in end
recv = clientSocket.recv(1024)
print 'recv:',recv
if recv[:3] != '220':
print '220 reply not received from server.'
# Send HELO command and print server response.
heloCommand = 'HELO Alice\r\n'
clientSocket.send(heloCommand)
recv1 = clientSocket.recv(1024)
print 'recv1:',recv1
if recv1[:3] != '250':
print '250 reply not received from server.'
# Send MAIL FROM command and print server response.
# Fill in start
fromCommand = "MAIL FROM:\r\n"#匿名邮件的「发送人」，可以随意伪造
clientSocket.send(fromCommand)
recv2 = clientSocket.recv(1024)
print 'recv2:', recv2
# Fill in end
# Send RCPT TO command and print server response.
# Fill in start
toCommand = "RCPT TO:\r\n" #收件人地址。
clientSocket.send(toCommand)
recv3 = clientSocket.recv(1024)
print 'recv3:', recv3
# Fill in end
# Send DATA command and print server response.
# Fill in start
dataCommand = "DATA\r\n"
clientSocket.send(dataCommand)
recv4 = clientSocket.recv(1024)
print 'recv4:', recv4
# Fill in end
# Send message data.
# Fill in start
clientSocket.send(msg)
# Fill in end
# Message ends with a single period.
# Fill in start
clientSocket.send(endmsg)
# Fill in end
# Send QUIT command and get server response.
# Fill in start
quitCommand = "QUIT\r\n"
clientSocket.send(quitCommand)
recv5 = clientSocket.recv(1024)
print 'recv5:', recv5
# Fill in end
clientSocket.close()
