I have absolutely zero experience with Python socket programming. I am basically learning as I go. Anyway, my instructor gave us an assignment to create a mail client using the skeleton code provided here: http://www.cs.wm.edu/~dnguyen/cs335/project/emailclient.pdf (NOTE: I do not attend WM.)
We are not allowed to use smtplib. I'm using Gmail to send email for this exercise, and upon further reading, I found that I have to use STARTTLS and then use SSL's wrap_socket(), then send EHLO again. This is the output I am getting and I have no idea what to do with it. I read somewhere on SO that the last 250 line means something as it has no hyphen/dash (-) between 250 and the text.
220 mx.google.com ESMTP z15sm36730pdi.6 - gsmtp
250-mx.google.com at your service, [xxx.xxx.xxx.xxx]
250-SIZE 35882577
250-8BITMIME
250-STARTTLS
250-ENHANCEDSTATUSCODES
250-PIPELINING
250-CHUNKING
250 SMTPUTF8
220 2.0.0 Ready to start TLS
Below is just part of my code. Since this is an individual assignment, I don't want to post the entire code for others in my class. If you would like to see additional code, please ask.
starttls = 'STARTTLS\r\n'
clientSocket.send(starttls)
recv2 = clientSocket.recv(1024)
print recv2
sslClientSocket = ssl.wrap_socket(clientSocket)
sslClientSocket.send(login)
getLogin = sslClientSocket.recv(1024)
print getLogin
sslClientSocket.send(password)
getPass = sslClientSocket.recv(1024)
print getPass
if recv2[:3] != '220':
print '220 tls reply not received from server.'
More code info: At the beginning of the file, I import ssl and base64. I define two variables 'login' and 'password' and used base64.b64encode() to encode those. The rest of the code is based on the skeleton code provided above. I send HELO before and after STARTTLS per this thread: Connect to SMTP (SSL or TLS) using Python
How do I read the output to determine what is going on? Thank you in advance for your help.
